Substitution

Показать описание
How to do substitution:
- First you are given the formula in the question
- Then numbers will be given, for example
- M = 4
- Then substitute in the values
- Then write the result
- Sometimes, they want you to re-arrange the formula to get a certain number, but this type of question will always have numbers to substitute
