number in an addition problem
answer to an addition problem
the number you are subtracting something from
the number being subtracted
the answer to a subtraction problem
the number that you multiply
answer to a multiplication problem
the answer to a division problem
the number being divided
tells how many equal parts to divide the number into
tells how many factors of the base to use (little number)
the number being multiplied (big number)
written with an exponent and a base
a sequence where you +/- the SAME number each time
a sequence where you multiply or divide by the SAME number each time
A fast way to write big numbers using powers of ten. Multiply a number with one digit to the left of the decimal point, by a power of ten.
Example- 1.7 x 103
math problem with numbers and operations
Example- 5 + 5 x 20
ORDER OF OPERATIONS
1.) parentheses 2.) exponents 3.) mult./div. 4.) add/sub.
you can change the order of the numbers when adding or multiplying, and get the same answer.
Example- 9 + 6 = 6 + 9
you can group the numbers differently when adding or multiplying, and get the same answer.
Example- 2 (5 x 4) = (2 x 5) 4
5(20 + 1) = (5 x 20) +(5 x1)
4(6-2)= (4 x 6) - (4 x 2)
any number x 1 = that number; any number + 0 = that number
Example- 1 x 6 = 6 0 + 6 = 6
a letter that stands for a number
math problem with numbers, variables, and operations
example- 5n + 6n
find the answer/ solve
part of an expression; separated by a plus or minus; can be a constant, variable, or a number multiplied by a letter.
Example- 1 + 2n + 3z
number multiplied by a letter (in front of)
an expression with an answer; a mathematical statement which states that two things are equal.
Example- 2 + N = 3
answer; makes the equation true
ADDITION PROPERTY OF EQUALITY
you can add the same number to both sides of an equation
+/- ; x/÷ operations that undo/check each other
SUBTRACTION PROPERTY OF EQUALITY
you can subtract the same number from both sides of an equation
MULTIPLICATION PROPERTY OF EQUALITY
you can multiply by the same number on both sides of an equation
DIVISION PROPERTY OF EQUALITY
you can divide by the same number on both sides of an equation
