PEMDAS=
1) Parentheses
2) Exponents
3) Multiplication/Division (work these from left to right)
4) Addition/Subtraction (work these from left to right)
4) Addition/Subtraction (work these from left to right)
If given the equation 4(3+2)-6+4, you would follow these steps:
1) Solve within parentheses, so 3+2=5 and your equation becomes 4(5)-6+4
2) There are no exponents...
3) Multiplication or division from left to right, so 4*5=20 therefore your equation becomes 20-6+4.
4) Addition and subtraction. Since we have more than one of these, we just do whichever is on the left first. So, 20-6=14, making the equations 14+4. Finally 14+4=18.
