1. 5 word prediction. Guess the meanings of the following words: Variable, expression, base, constant, & factor.
Why is it important to understand the “language” of mathematics? GSE Unit 1
Identifying Parts Guided NOTES
Can have variables, numbers, addition, subtraction, multiplication, division, parenthesis, square roots, exponents… Examples:
Symbols or letters used to represent an unknown Examples:
How many items are being added, subtracted, divided Examples: 3 4
Same variable raised to the same power Examples:
The number in front of a variable Examples: 123 9 1
The number up in the air next to a base The number of times you multiply something times itself Examples: 3 12 4
What the exponent sits on The part that has been raised to a power Examples: 2 x y
A number that has no variable It can be positive or negative Examples: -42 5 -8
Items that are being multiplied together Can be numbers, variables, parenthesis Examples: 1 and 6…. Or 2 and 3 9 and x and y (x + 2) and (y – 3) 3 and (z – 9)
Simplify inside parenthesis Take care of exponents In order from left to right, multiplication or division In order from left to right, addition or subtraction Examples: -18
Sum Plus Add More Than Increased Together
Difference Minus Decreased Less Than (swaps the order) Take away
Quotient Half Divide by
Product Twice Double Triple Times
Square Cubed To the power of Raised to a power
The sum of a number and 10 x + 10
The product of 9 and x squared 9x 2
9 less than g to the fourth power g 4 – 9
8 + 3x Eight increased by three times x
2. Four times a number plus 10 minus two times the same number is 6. 1. Five times a number increased by 5 is the same as 3 times the same number decreased by 7.
