Answer:
-7
Explanation:
The rule for subtraction, in this case it is -5-3, you change the subtraction sign to addition and use the opposite of the second number, making it -5+(-3) which is -8. Then, you add 1 to -8, and the rule for this specific expression is to take the absolute value of both -8 and 1, then subtract the two, making the expression as of now 8-1. Subtract them, and get 7, but you take the sign of whichever number had the greatest absolute value, which was -8, so now the answer is -7. That's how you get your answer
-5-3+1= -5+(-3)+1
-8+1= |-8|-|1|
8-1= -7 (because you take the sign with the greatest absolute value, which is -8.)
