1 6 th Grade Unit 3 Vocabulary By Drew Levine

2 Algebraic expression An algebraic expression is when you can use any numbers for that problem and you replace them with letterers Examples Ax0=0 Ax1=A (A+A)x3=3x(A+A)

3 Cell, Column and rows Cells are the boxes. a column is the part going up and down. Rows are the boxes that go side to side.

4 Formula RxRx3.14=A Lx2+hx2=perimeter

5 General pattern A general pattern is when the sum is different then the sum for an Example 90+(-90)=0

6 Rate Rates are used to show date over time also to can compare different things in the corner you can see they are comparing 3 different things

7 Special case A special case is an exception to a rule or an easier way to solve a problem. X 2 - 9=(x+3)(x-3)

8 Square root The square root is when you take a number and find that it multiplied by its self = that number. Examples The square root of 9 is 3 100 is 10 81=9 64=8

9 Unit rate The denominator of a fraction is 1 of something. For example, I get paid $8.51 an hour 8.51/1 My car goes 70 miles an hour.70/1

10 variable A variable is a symbol or letter that is used to represent a number in a math equation. X+9=12
