Friedyokes: How do you explain the contextual meaning of "order" to a nursery school pupil? |

phililp: You're quite right. According to the Encyclopedia of Mathemathics: The BODMAS acronym is for: Brackets (parts of a calculation inside brackets always come first). Orders (numbers involving powers or square roots). Division. Multiplication. Addition. Subtraction. |

LionDeLeo:u have left justifying that 'of' means multiplication nd now u r saying the children are too young ...we were taught bodmas from primary school through junior secondary and not once did any of our teachers make the correction or are u saying that a primary 6 or jss student can't handle it ? 1 Like |
Re: Our Maths Teachers Must Apologise To Us by LionDeLeo: 11:22pm On May 08, 2017 |
Friedyokes: Nay! You are missing the point. What I mean is that both "of" and "order" mean the same thing, in principle. And as such, our teachers are very correct. Infact, even from your little example, I can prove to you that multiplication and division mean same thing. Same applies to addition and subtraction, same. Also, it can be argued that addition and multiplication are exactly the same. Just as division and subtraction also mean same thing. So, generally, all mathematics operations are just same just that for simplicity, they are differentiated. But some are more interchangeable with others like "order" and "of". |

Multiplications and Divisions mean the same thing? Let's put this absurd theory to the test. If you multiply a division, you end up back where you started. If you start with 4, and you divide it into 2, then multiply 2, you end up right back with 4. So how can multiplication and division mean the same thing? Does that even make sense? |
Re: Our Maths Teachers Must Apologise To Us by Friedyokes: 11:28pm On May 08, 2017 |
LionDeLeo:let's say I agree with u that 'of' nd 'order' mean the same thing are u going to tell me that in all u years of school without checking u interpreted 'of' as square root?...because although I found it weird ...I nd i assume a lot of students interpreted 'of' as a preposition in bodmas |
Re: Our Maths Teachers Must Apologise To Us by LionDeLeo: 11:30pm On May 08, 2017 |
Friedyokes: Modified, with addition. "Of" has always meant "multiplication" I have always known this. LionDeLeo: |

TheLogicalMind: Dude, find a way of getting out of my mention. I'm talking with a member who knows what he is doing. Now, get out. |
Re: Our Maths Teachers Must Apologise To Us by Friedyokes: 11:41pm On May 08, 2017 |
LionDeLeo:if 'of' in bodmas means multiplication why is it written differently...if addition means subtraction why was it written differently in BODMAS if you are telling me that 'of' 'square root' and multiplication mean the same thing what then is the point of Bodmas shouldn't it be bdmas or are u saying they added it for its pronunciation My point in essence was that teachers telling us 'of' was misleading ...it would've been better if they had said order ...nd if we asked they'll tell us when we go higher we will understand (an excuse they gave all the time ) |

LionDeLeo: Talking with a member who knows what he is doing? More like being schooled by a member who knows what he's doing. Too bad that the degrees they hand out like candy in Usman Dan Fodio University don't come with disclaimers written on them ![]() |

Friedyokes: Actually, the point there is that, in teaching, methodologies and consideration of phase are of critical importance. There are things which we were taught at elementary levels which as we proceeded further in studies, we discovered they are not true, but teaching them in that fashion is very correct. Example. In junior secondary schools, what was the definition of atom. We were told that they are the smallest indivisible particles that can take part in chemical reactions. But is that definition correct? No. Atoms are not the smallest indivisible particles and the components that actually take part in chemical reactions are not atoms but electrons and protons. Again, in primary schools, we were told that examples of nouns are chair, school, etc. But we later discovered that this is not true because you cannot say this is the part of speech a word belongs to until it is used in a sentence. That is a school. School is a noun here. But They school here. School is a verb here. While This is a school library. Here, school is an adjective. Hence, you classify a word based on the work it does in a sentence. That is, it must be used in a sentence first before you say if it is a noun or whatever. But what were we told? A noun is the name of person, place or thing. Examples of noun; chair, table, house. |

Friedyokes: Meanwhile, if you are interested, I can prove the equality of all the arithmetic operations I have mentioned. |
Re: Our Maths Teachers Must Apologise To Us by Friedyokes: 12:12am On May 09, 2017 |
LionDeLeo:let's say I agree with u that giving false information/deliberately misinforming impressionable students was very correct ...at what stage do u think that this misinformation needs to be corrected ..because I can say for fact till I left secondary school no teacher made the correction...nd yes if I had known that.. I would've seen equations involving simplification in a whole new light (example changing sub of formula : my teacher just told me that the roots should be removed fest if he had related it to bodmas it would've simplified things)....if till today u asked me what bodmas was I would've told u that 'of' is a preposition |
Re: Our Maths Teachers Must Apologise To Us by Friedyokes: 12:18am On May 09, 2017 |
LionDeLeo:if I am to agree with u that would mean that they are connected ...but then bodmas is still separating them ...so it is the responsibility of the teacher to explain to us and they didn't ..that's the problem |
Re: Our Maths Teachers Must Apologise To Us by LionDeLeo: 12:19am On May 09, 2017 |
Friedyokes: Well, the use of "of" even as a preposition, based on your own understanding is still not different from its exact meaning in mathematics. If for instance I say, 20% of 50, what do you think that connotes? Is it not still 20/100 × 50? Again, if I say, 2/3 of 60, is that not 2/3×60? So, even as a preposition, it still implies multiplication in mathematics. |
Re: Our Maths Teachers Must Apologise To Us by LionDeLeo: 12:21am On May 09, 2017 |
Friedyokes: But you may certainly be understanding it in a different perspective because I know some teachers may not know the exact meaning of the "of". But not knowing it doesn't mean that what they say is wrong. |
Re: Our Maths Teachers Must Apologise To Us by Friedyokes: 12:22am On May 09, 2017 |
LionDeLeo:by preposition there I mean I would never liken it to finding the squareroot or powers |
Re: Our Maths Teachers Must Apologise To Us by Friedyokes: 12:25am On May 09, 2017 |
LionDeLeo:they were wrong in not telling us what it means which is their entire job description |
Re: Our Maths Teachers Must Apologise To Us by LionDeLeo: 12:26am On May 09, 2017 |
Friedyokes: The equality between "of" and "order" has been discussed. But did you liken it to multiplication, based on this last post you quoted? |
Re: Our Maths Teachers Must Apologise To Us by LionDeLeo: 12:26am On May 09, 2017 |
Friedyokes: Not telling you that it is multiplication or order? |
Re: Our Maths Teachers Must Apologise To Us by Friedyokes: 12:29am On May 09, 2017 |
LionDeLeo:discussed not agreed upon ....Yes in that context of is multiplication |
Re: Our Maths Teachers Must Apologise To Us by LionDeLeo: 12:31am On May 09, 2017 |
Friedyokes: Okay, the issue now is how is "of" same as "order"? |
Re: Our Maths Teachers Must Apologise To Us by Friedyokes: 12:32am On May 09, 2017 |
LionDeLeo:not telling us either ..they simply ignored it ..till we left school ....nd it being multiplication is still debatable ..saying square root and powers means multiplication is just confusing |
Re: Our Maths Teachers Must Apologise To Us by LionDeLeo: 12:34am On May 09, 2017 |
Friedyokes: Two things at the same time. One at a time. First, what is 4^2? As in 4 to the power of 2 |
Re: Our Maths Teachers Must Apologise To Us by Friedyokes: 12:34am On May 09, 2017 |
LionDeLeo:no the issue is that they made no effort to explain what 'of' in bodmas means leaving us to assume it is of no use |
Re: Our Maths Teachers Must Apologise To Us by LionDeLeo: 12:38am On May 09, 2017 |
Friedyokes: Now, what exactly is your argument? Cos I'm not really understanding. That they did not explain the meaning of "of" or that the "o" is not "of" but "order"? |
Re: Our Maths Teachers Must Apologise To Us by Friedyokes: 12:40am On May 09, 2017 |
LionDeLeo:okay see what you are doing ...you are explaining to me ...my point is that they didn't ...which leads me to believe that they did not know and if they did not know ...the 'of' which we were taught in the manner we were taught does not relate to multiplication or square root or powers...which makes them wrong |
