Math Unit 1 THIRD

the representation of a number as a sum that shows the value of each digit

to find the nearest value of a number based on a given place value

< a relationship showing that the value on the left is less than the value on the right

operations that undo each other

a mathematical process such as addition, subtraction, multiplication, and division

symbols that are used to group numbers. show which operations to complete first

if you add zero to a number, the sum is the same as the given number

a number close to an exact value. Indicates about how much

the property that states that the order two numbers are multiplied does not change the product

o use place value to exchange equal amounts when renaming a number

the form of a number that uses written words

the property that states that the grouping of the addends does not change the sum

a missing number, or the number to be solved for

the value given to a digit by its place in a number

a symbol used to write a number

within the bounds of making sense

a sequence of numbers, figures, or symbols that follow a rule or design

= a relationship showing that the value on the left is equal to the value on the right

ordering or grouping numbers so that they are easier to compute in your head

the usual way of writing a number that shows only its digits, no words

> a relationship showing that the value on the left is greater than the value on the right
