Question | Answer |
---|---|
distributive property | Example: 5*(3+4)=5*3+5*4 |
identity property of addition | states that the sum of zero and any number is that same number 5+0=5 |
commutative property of addition or multiplication | states that if the order of the addends or factors is changed, the sum or product remains the same 6*7=7*6 |
zero property of multiplication | states that the product of any number and zero is zero 2*0=0 |
associative property of addition and multiplication | states that changing the grouping of the addends or factors does not change the sum or the product |
identity property of muliplication | states that the product of a number and one is that same number 9*1=9 |
evaluate | to find the answer or value of an expression |
exponent | the number that tells how many times a factor(base) is to be multiplied together |
variable | a letter or symbol that stands for an unknown number x + 3 = 18 x=15 |
clustering | a method of estimation used when all the addends are about the same 52+49+51 about 50*3 |
numerical expression | a phrase used in math that contains only numbers and operation symbols 5*7+4 |
compatible numbers | pairs or groups of numbers that are easy to compute in your head 4*25*8 |
estimate | an approximate answer after rounding two or more numbers 27 + 57 is about 30+60=90 |

decimal | another way of writing a fraction which is part of a whole |
composite number | a whole number greater than 1 that has more than two factors |
prime number | a whole number greater that 1 that has only two factors,1 and itself |
greatest common factor | the greatest divisor that two or more numbers have in common |
least common multiple | the smallest multiple that two or more number have in common |
prime factorization | a number divided into the product of all its prime factors 24=2*2*2*3 |
base | the number that is with an exponent which is used as the repeated factor 5*5*5=5^3 |
compensation | used in estimating when you change one number to a multiple of ten and adjust the other number to keep the balance 27+18= 30 +15=45(added 3 to 27 and subtracted 3 from 18) |
