Answer:
8
Step-by-step explanation:
1. multiply 5 and 12 to get 60
2. multiply 5 and m to get 5m
3. the equation would be 60 + 5m = 100
4. next, subtract 60 on both sides
5. your equation so far is 5m = 40
6. then divide 5 on both sides
7. then you have your answer m = 8
I think you have to follow someone and ask them to be your tutor.

Answer:
Get a calculator
Step-by-step explanation:
Most of the time for simple math like multiplying 2 digits, it is easiest if you just get a calculator. It saves a lot of time.
If you can't get a calculator then i recommend memorizing some common equations.
For example 10*15= 150
so that if you get 12*15=?, you can easily just add two extra 15's to your answer of 150.
15+15 is 30, and 30+150(from 10*15)=180.
Therefore 12*15=180.
:) Hope that helped!
