Vocabulary

Explain – to give a clear, understandable explanation or answer

Justify – to lay out the mathematical process step-by-step, showing all work.

Equation – a sentence that says 2 expressions have the same value (=).

Inequality – a sentence that compares the values of 2 expressions, but doesn’t say they are strictly equal. <,>, ≤,≥

Numerical Expression – a mathematical phrase that contains numbers and operations. Ex: 8+7

Algebraic Expression – a mathematical phrase that contains numbers, variables, and operations. Ex: 8+7x

Simplify – Replaces the expression with an equivalent expression that is simpler. Ex: 8x+2x=10x

Vocabulary

Solve – to obtain the answer/solution to an equation.

Evaluate – To find the value by following the instructions. Ex: Evaluate 8+7, 8 plus 7 is 15. Ex: Evaluate 8+y, when y=7 8+7=15

Solution – a number that makes the equation true.

Vocabulary

Vocabulary

Variable – a symbol, most of the time a letter, that represents a number. Ex: 8x – “x” is the variable

Co-efficient – the term(number) in front of the variable. Ex: 8x – “8” is the co-efficient

Equivalent – 2 expressions that are equal

Vocabulary

Squared – multiplying a number times itself. Ex: 22 - 22 = 4

Cubed – a number multiplied by itself 3 times. Ex: 23 - 222 = 8

Understanding expressions

It is really important to understand what signs really mean. To practice understanding signs, you are going to complete #17 – 22 in your packet. You are going to write out in words what each expression means.

#17 – Fourteen minus eight equals six

Understanding expressions

Now, in questions 23-30 we are going to practice transforming words into a numerical or algebraic expression.

#23 – 13 + 7 = 20

Seven is more than 13. 13 is your starting point.
