**P**

Perform operations inside grouping symbols. Grouping

symbols include parenthesis () brackets [] and

braces {}. Always work from the innermost part to

the outermost: INSIDE OUT.

Simplify Powers

Exponents need to be taken care of before other operations.

Application:

Hank Aaron's last season in the Major Leagues was 1976. A player's total number of bases can be found by multiplying the number of singles by one, doubles by two, triples by three and homeruns by 4 and then finding the sum. If Aaron hit 44 singles, 8 doubles and 10 homeruns in his final season, find his total bases for 1976.

*Remember to be careful with your negatives!!!

From this, we can get the equation:

44(1) + 8(2) + 0(3) + 10(4)

Singles

Then we use order of operations.
