Excellent.
You can also perform the same trick on decimals.
E.g
0.2 x 0.4 = 0.08
Remove d decimal points (2 x 4 =
Count d numbers of zeros in both decimals I.e 0.2 n 0.4 has 2 zeros
Add the 2 zeros to ur answer from d left hand side. I.e 0.08

very true. All these short cuts make maths quite easy.

2 and 3 will not work for larger numbers tho

[quote author=3Dee post=36519564]

It works for 3

Hope it works when u want to solve other numbers

good

Rukemi291:
For multiplying figures with Zero, remove the zeros and multiply the figures then put back the zeros.

eg.
500x200
5x2=10 then add four zeros

100000.

Nice one.

we were taught some of them in the olden days, like multiplying any number by 11 and the Celsius to Fahrenheit conversion.

Do u knw I can't even do a simple arithmetic without a calculator, d modern system of education sucks.
So annoying

10. Remembering Greater Than and Less Than Symbols

Actually, my teacher did teach us this one. She actually said that we should imagine it's a crocodile that wants to eat the bigger number.

I did figure out the 9 multiple one on my own when I was a kid.

I didn't know any of the others, but they're cool!

Thanks so much; you are a great nairalander.
