What do we do first???? It Matters!!!! =
The Order of Operations 1. Parenthesis 2. Exponents 3. Multiplication & Division (left to right) 4. Addition & Subtraction (left to right) 5. Simplify any Fraction All of Algebra is Based on…
What do we do first???? =
The Order of Operations 1. Parenthesis 2. Exponents 3. Multiplication & Division (left to right) 4. Addition & Subtraction (left to right) 5. Simplify any Fraction Memorize These
Example (-8 + 5) (-3) (-3) Holy Mackerel
Example 2
Evaluate when a = -2, b = 4 (2a) 2 - 3b 2 (-4) 2 - 3(4) (16) (2-2) Evaluating Algebraic Expressions 16 + (-48)
Evaluate when x=7, y=-3 x 2 - 2y 2 + y ( - 3) (9) More “Placeholders”
Evaluate when x = -5, y = -2 x 2 - 2y 2 + y (- 5) 2 - 2( - 2) (4) Variables can “Vary”
Looks Easy BUT… Evaluate when a = -2 -a2-a2 2 only has power over the a (not the negative sign)
Try some on your own...
