Section for warm up exercises on adding and subtracting.
In this exercise we're asked to do basic addition.
We are told the question in English and then we are given a FORMULA that we can use to calculate our answer.
The question is easy enough that you don't need a formula but when questions become less easy to understand a formula is very useful.
Which is why we are using them now.
(#Mary has) Means how many apples Mary has.
(#more John has) Means how many MORE apples John has than Mary.
The formula tells you to add these two values together.
Answer 13+ 11
= 24
John has 13 more apples than Mary.
If Mary has 11 apples, how many apples does John have ?
(#Mary has) + (#more John has)
