−45−(8+10)= -45-(8+10)= −45−(8+10)=
According to the order of operations, first we solve the exercise within parentheses:
8+10=18 8+10=18 8+10=18
Now we obtain the exercise:
−45−(18)= -45-(18)= −45−(18)=
We open the parentheses, remember to change the corresponding sign:
−45−18=−63 -45-18=-63 −45−18=−63
−63 -63 −63
