tells us which operation to
perform first, when there
is more than one
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.

INSIDE OUT again.
Multiply and Divide from left to right.

LEFT to RIGHT.
Remember: always from LEFT to RIGHT...

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.

= -12

*Remember to be careful with your negatives!!!
From this, we can get the equation:
44(1) + 8(2) + 0(3) + 10(4)
Singles
Doubles
Triples
Homeruns
Then we use order of operations.
= 100
