-8(2×2)+3×7+(-2)
At first we have to do multiplication in parentheses::
"2\u00d72=4,"
so we have:
"-8(2\u00d72)+3\u00d77+(-2)=-8\u00d74+3\u00d77+(-2)."
The next we have to do 2 multiplications:
"-8\u00d74=-32,"
"3\u00d77=21."
So:
"-8\u00d74+3\u00d77+(-2)=-32+21+(-2)="
"=-(32-21)+(-2)=-11+(-2)=-13."
Answer: -13.
