Answer:

10 - 4 - 3 - 2 = 1

10 - 4 - (3 - 2) = 5

10 - (4 - 3) - 2 = 7

10 - (4 - 3 - 2) = 11

Explanation:

For each equation, we can insert the brackes as follows

10 - 4 - 3 - 2 = 1

10 - 4 - (3 - 2) = 10 - 4 - 1 = 5

10 - (4 - 3) - 2 = 10 - 1 - 2 = 7

10 - (4 - 3 - 2) = 10 - (-1) = 10 + 1 = 11

Therefore, the answers are:

10 - 4 - 3 - 2 = 1

10 - 4 - (3 - 2) = 5

10 - (4 - 3) - 2 = 7

10 - (4 - 3 - 2) = 11
