Simply 8 - (-5) - 4 (-7)

41

Step-by-step explanation:

8 - (-5) - 4 (-7)

First, a number minus a negative number is the same as adding a positive number:

8 + (+5) - 4 (-7) or 8+5-4 (-7)

Next, you have to multiply - 4 and - 7:

8+5+28 (a negative times a negative is a positive)

Add together:

13+28=41

Therefore the answer is 41

41

Step-by-step explanation:

4 (-7) is 4 * - 7 which equals - 28

8 - (-5) can be changed to 8 + 5 which equals 13

13 - - 28 can be changed to 13 + 28 which equals 41
