Question	Answer
Rounding all the way	Process to estimate actual answer. When rounding all the way, only one nonzero digit is left. Rounding all the way gives the least degree of accuracy, 6, 9. Example: 1,251 to 1,000; 2,995 to 3,000.
Addends	Numbers that are combined in the addition process, 9. Example: 8 + 9 = 17, in which 8 and 9 are the addends.
Sum	Total in the adding process, 9.
Minuend	In a subtraction problem, the larger number from which another is subtracted, 10. Example: 50 – 40 = 10
Subtrahend	In a subtraction problem, smaller number that is being subtracted from another, 10. Example: 30 in 150 − 30 = 120
Difference	The resulting answer from a subtraction problem, 10. Example: Minuend less subtrahend equals difference. 215 − 15 = 200.
Multiplicand	The first or top number being multiplied in a multiplication problem
Multiplier	The second or bottom number doing the multiplication in a problem
Product	Answer to a multiplication process
Partial products	Numbers between multiplier and product
Divisor	Number in the division process that is dividing into another, 13. Example: 15 ÷ 5, in which 5 is the divisor.
Dividend	Number in the division process that is being divided by another, 13. Example: 15 ÷ 5, in which 15 is the dividend.
