- 1. property of multiplication – if multiplying a number by a sum of numbers, the product will be the same as multiplying the number by each addend and then adding the products together; a × (b + c) = (a × b) + (a × c)
- 4. the number the dividend is being divided by
- 7. the size or measure of each group or the number of groups when the dividend is divided by the divisor
- 12. the rules of which calculations are performed first when simplifying an expression
- 13. the number that is being divided
- 14. symbols to show a group of terms and/or expressions within a mathematical expression
- 15. a number in the base-10 place value system used to represent a quantity that may include part of a whole and is recorded with a decimal point separating the whole from the part
- 16. a mathematical phrase, with no equal sign or comparison symbol, that may contain a number(s), an unknown(s), and/or an operator(s)
