Problem 1:
> There are 50 roses in the garden. If 18 of them are red and 12 are white, how many roses are of other colors?
Solution:
We know the total number of roses is 50.
Red roses = 18
White roses = 12
To find roses of *other* colors, subtract the red and white roses from the total:
50 – 18 – 12 = 20
✔ Answer: 20 roses are of other colors.

Problem 2:
> Ella bought a box of colored markers that contains 30 markers. She gave 8 markers to her sister. How many markers does Ella have now?
Solution:
Ella started with 30 markers.
She gave away 8.
So, we subtract:
30 – 8 = 22
✔ Answer: Ella has 22 markers now.

Problem 3:
> There are 36 books on a shelf, and 24 of them are fiction books. How many books are non-fiction?
Solution:
Total books = 36
Fiction books = 24
Non-fiction books = Total – Fiction
36 – 24 = 12
✔ Answer: 12 books are non-fiction.
