You would need to go in the order of pemdas
Step-by-step explanation:
I would say teach them easy stuff like 5+5 and number problems such as Sarah has 10 apples and takes away five apples,How many apples does Sarah have now?
N - the number
14 + n = 17 |subtract 14 from both sides
n = 3
It’s A. 45.
hope this helps
