 addend the numbers added in an addition problem.... 3 + 5 = 8 3 and 5 are addends addition to join or combine two or more more numbers to get a bigger number approximately to estimate an amount or total, often by rounding to the nearest ten, hundred, or thousand...close to a number combine to put numbers or objects together...it would indicate addition compare to describe as similar, equal, less than, greater than, alike, not alike comparison the act of comparing objects or numbers compute to find an answer using math computation the act of computing or the act of finding an answer using math consecutive numbers that follow each other in an unbroken sequence 1, 2, 3, 4, or 3.4, 3.5, 3.6 decrease to become smaller in size or number difference the answer in subtraction digit a symbol used to show a number 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 dividend the number being divided in a division problem 20 divided by 5 = 4 20 is the dividend divisor the number the dividend is being divided by 20 divided by 5 = 4 5 is the divisor equation a mathematical sentence where the left side of the equals sign has the same value as the right side estimate to find out about how much often by rounding numbers before solving the problem estimation the act or process of estimating to find an answer usually by rounding even number a number that can be exactly by 2 which means it must end with 0, 2, 4, 6, or 8 expanded form a way of writing numbers to show the value of each digit in the number factor a whole number that divides exactly into another number increase to become larger in size or number inverse opposite operations... addtion is inverse of subtraction and mutliplication is the inverse of division minimum the lowest or least amount or value maximum highest or greatest amount or value multiplication a mathematical process where a number is added to itself a number of times division sharing or dividing a number into a group of equal parts odd number number that cannot be exactly divided by 2 and must end in 1, 3, 5, 7, or 9 place value the value of a digit, depending on its place in a number product the answer or result when two or more numbers are multiplied quantity amount or number of something quotient the number resulting from dividing one number by another number...the answer in division remainder the amount left over after dividing one number by another number round change a number to a number that is easier to use by changing it to the nearest ten, hundred, etc. sum the total or whole amount... the result or answer when adding base ten a number system using the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 in different place values of a number convert to change to something of equal value compatible numbers numbers that are easy to work with from rounding, or easy to use because of number facts computation the process of figuring out or solving number problems equal to` having the same amount equation (number sentence) a number sentence where the left side of the equal sign is the same as the right side of the equal sign equivalent alike or equal in number greater than > more than another number or amount greatest the biggest or largest horizontal going across as parallel to the floor justify to prove least the smallest less than < smaller than multiple adding a number to itself or counting by a number as mutiples of 2 are 2, 4, 6, 8, 10, 12.... place value chart a chart showing the order of the value of numbers by their place in the number quotient the answer to a division problem range the amount between the lowest number and highest number in a list of numbers reasonable what you would expect when working out a problem sequence an ordered set of number or shapes according to a pattern standard form numbers written using the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 subtraction the act of taking one amount away from a larger amount variable able to change vertical going up and down as a wall goes up and down
