2) Order of Operations
1) Parentheses (Grouping Symbols) (7 – 4)² + 3 • 5
2) Exponents = 3² + 3 • 5
3) Multiply or Divide, from left to right = 9 + 3 • 5
4) Add or Subtract, from left to right = 9 + 15

3) Decimals – Adding and Subtracting
1) Line up decimal points, if it does not have a one, it is a whole number with the decimal point at the end.
2) Use zeros to hold empty places.
3) Add or subtract vertically.
4) Bring down the decimal point.

4) Decimals: Multiplying and Dividing
Multiplying
1) Line up digits, starting on the right.
2) Multiply
3) Place the decimal point in the answer by starting at the right and moving a number of places equal to the sum of the decimal places in both numbers multiplied.
(6.432)(4.15) 6.432 (3 decimal places) x 4.15 (2 decimal places) 32160 64320 2572800 26.69280 (5 decimal places)
Dividing
1) If the divisor is not a whole number, move the decimal point to the right to make it a whole number and move the decimal point in the dividend the same number of places.
2) Divide.
3) Bring the decimal point up.

5) Integers: Adding and Subtracting
Addition - SAME SIGNS -4 + (-5)
1) Add their absolute values. 4 + 5 = 9
2) Attach the common signs. -4 + (-5) = -9
Addition - OPPOSITE SIGNS 3 + (-9)
1) Subtract the smaller absolute value from the larger.
(9 – 3) = 6
2) Attach the sign of the number with the larger absolute value.
3 + (-9) = -6
Subtraction
1) Adding the opposite of a number is equivalent to subtracting the number.
2) Change all problems to addition and follow the addition rules.
3 – 12 = 3 + (-12) = -(12 – 3) = -9
- 7 – 1 = -7 + (-1) = -(7 + 1) = -8
-4 – (-10) = -4 + 10 = +(10 – 4) = 6
12 – ( -8) = 12 + 8 = 20

6) Integers: Multiplying & Dividing
Same Signs: If two numbers have the same sign, their product or quotient is positive.
(-7)(-5) = 35 6 • 8 = 48
Different Signs: If two numbers have opposite signs, their product or quotient is negative
