There are several types of flowers in a field.
5 flowers grow on one bush and there are are 13 such bushes.
Another area has 9 plants, each of which has 2 flowers.
The flower pickers took 30 flowers from the bushes and 10 from the plants.
How many flowers are left in the field?
We will convert the question into an exercise with which we are familiar:
(5×13−30)+(9×2−10)
First, we will solve everything that is in the parentheses, starting with the multiplication and division from left to right:
(65−30)+(18−10)
Then the addition and subtraction operations that are in the parentheses:
35+8
Finally, we perform the operations outside of the parentheses:
35+8=43
