Question

Find 3×12 using two different methods. Which method do you find more efficient?

Answer 1

Explanation:

heyy!

so you could either add

~ 12 + 12 + 12

which gives us 36

or

~ 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3

which also gives us 36

orrrr you could multiply

~ 3 x 12

which gives us 36

personally, i find multiplication to be much more efficient and way quicker!
