I can't remember the steps to working an algebra problem like this. Thanks
what are the steps for working 20-(9-3)
I use PEMDAS when I'm trying to remember the steps you take to solve an algebraic equation, i.e., the order of operations . You solve in this order:
P: parentheses (work inside the parentheses first)
E: exponents (then apply the exponents)
M/D: multiplication/division comes next
A/S: addition/subtraction come last
Always do the part of the equation in teh parentheses first. You have 20-(9-3), which you'd simplify to 20-6. The asnswer would be 14.
