Explanation:

Step1: Analyze the groups of strawberries. There are 4 groups of 5 strawberries and 1 group of 2 strawberries. So one way is to calculate 4 times 5 plus 2.

$4\times5 + 2$

Step2: Calculate the value. $4\times5 = 20$, then $20 + 2 = 22$.

Another way: Consider 5 groups of 5 strawberries and subtract 3 (since the last group is 2 instead of 5, we subtract 3). So $5\times5 - 3$.

Step3: Calculate the value. $5\times5 = 25$, then $25 - 3 = 22$.

Answer:

$4\times5 + 2 = 22$; $5\times5 - 3 = 22$
