Addition is when theres is a certain nuumber of something example 5 apples and there are 5 oranges and you want something that makes 10 so count them together 5 + 5 = 10

subtraction is when there 10 apples and you eat one and then you count it and 9 so you took one away by eating it 10 - 1 = 9

18) Makala bought 9 plums and we know that they were 7 fewer than Trin.

So that means Trin bought 7 more than Makala.

We can add 9 and 7 to find how many plums Trin bought.

9 + 7 = 16

Trin bought 16 plums.

19) Joey gave 8 peanuts and he has 7 left. To find the total number of peanuts he had can be found by adding 7 and 8.

7 + 8 = 15

There were 15 peanuts in all.

20) We need to find the total number of animals so we will just add all the animals.

6 + 4 + 4 = 14

There are 14 total animals in the park.

21) Clint picked 13 apples and Tim picked 5 less. So subtract 13 and 5 to find the number of apples Tim picked.

13 - 5 = 8

Tim picked 8 apples.

Hope this helps :)

methodology: the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly
