Question

Solve these problems

43+(-56) minus 78
-78 minus 65
-19 minus 4
-16 + 9
71 + (-18)

Answer 1

Explanation:

43+(-56)minus 78= negative 91

43+-56= - 13 13-78= negative 91

-78 subtract 65=143 because when your in negatives it is opposite so when you subtract it is addition so what is -30 add 50=20. So what is -78 subtract 65=143

-19 subtract 4 =-23 because like I said in negatives it's opposite.

-16+9=7.

And last 71 + -18=53 because it is subtracting 18 since it is negatives.

Hope it helps :)
