1. Step-1: If we are following the standard order of operation then anything come inside the parentheses should be done first: (423+682-563-90) Step-2: Inside of a parentheses addition should be done first then subtraction: 423+682=1105 -563-90=-653 (423+682-563-90)=(1105-653)=452 Step-3: If there anyRead more

    Step-1:
    If we are following the standard order of operation then anything come inside the parentheses should be done first:
    (423+682-563-90)
    Step-2:
    Inside of a parentheses addition should be done first then subtraction:
    423+682=1105
    -563-90=-653
    (423+682-563-90)=(1105-653)=452
    Step-3:
    If there any operation other than parentheses it only comes after it. Therefore division comes after this:
    so the final answer is = 452รท5=90.4
