Order of Operations

Taking into account order of operations is an important step in developing your algebra skills. Remember PEMDAS, which guides the order of operations to begin with parentheses, then exponents, multiplication, division, addition and finally subtraction. Let’s try a tough one:

First, take care of the inner-most parentheses by squaring -3. That’ll give us 9. Then, subtract 9 from 4, which gives us -5. Now square that and we have our answer of 25.
