Final answer:
To rewrite the subtraction expression (-2) - (-5) as addition of the opposite, you need to change the sign of the second number, and then solve by adding the two numbers together. The final solution is 3.
Step-by-step explanation:
The expression (-2) - (-5) can be rewritten as (-2) + (-(-5)). To solve this, we need to change the sign of -5 to its opposite, which is +5. Therefore, the expression becomes (-2) + 5.
Now, we can solve this by adding -2 and 5 together. When adding two numbers with opposite signs, we subtract the smaller number from the larger number and use the sign of the larger number.
In this case, 5 is larger than -2, so we subtract -2 from 5 and keep the sign of 5, resulting in 5 - 2 = 3.
Therefore, (-2) - (-5) = 3.
