How do you mutiply?

Answer 1

how to multiply:

1. the 0s trick : any number * 0 always = 0

2. the 1s trick : any number * 1 is the number you mutiplyed. for example, 678*1=678 or 34*1=34

3.the 2s trick : any number * 2 is an even number. for example, 30*2=60

it's just like adding 2 of the same numbers together. for example, 30*2=60 & 30+30=60

there is no 3s trick or 4s trick

4.the 5s trick : count by 5s, 5*2=10, 5+5=10
