Problem Analysis

The problem states that Masha received a certain number of carnations from her classmates. She gave some carnations to her mother and some to her grandmother. We need to determine how many carnations Masha has left. To solve this problem, we need to assign values to the variables a, b, and c and calculate the result.

Solution

Let's assign the following values to the variables: - a: the number of carnations Masha received from her classmates - b: the number of carnations Masha gave to her mother - c: the number of carnations Masha gave to her grandmother

To find out how many carnations Masha has left, we need to subtract the number of carnations she gave to her mother and grandmother from the total number of carnations she received. The expression for the number of carnations Masha has left is:

a - b - c

Let's calculate the result using some example values for a, b, and c.

Example Calculation

Let's assume Masha received 10 carnations from her classmates (a = 10), gave 3 carnations to her mother (b = 3), and gave 2 carnations to her grandmother (c = 2).

Using the expression a - b - c, we can calculate the number of carnations Masha has left:

10 - 3 - 2 = 5

Therefore, Masha has 5 carnations left.

Answer

If Masha received a total of a carnations from her classmates, gave b carnations to her mother, and gave c carnations to her grandmother, the number of carnations she has left is given by the expression a - b - c.

Please note that the values of a, b, and c can vary depending on the specific scenario.
