OSAT Subtest 2: Math || All Solved.
order of operations correct answers the order in which operations in an expression to be
evaluated are carried out. 1. parentheses 2. exponets 3. multiplication and divison 4. addition and
subtraction
PEMDAS
prime number correct answers can be divided evenly only by 1 or itself ex: 5
Identity Property of Addition correct answers a + 0 = a
5+0=5
distributive property correct answers a multiplication fact that can be broken up into the sum of
two other multiplication facts
23 x 2 =
(20 + 3) x 2 =
(20 x 2) + (3 x 2) =
40 + 6 = 46
Commutative Property of Multiplication correct answers you can multiply the factors in any
order and the product will be the same
5 x 4 = 20
4 x 5 = 20
, Commutative Property of Addition correct answers Changing the order of the addends does not
change the sum
a+b
b+a
2+3=5
3+2=5
Associative Property of Addition correct answers Changing the grouping of three or more
addends does not change the sum
(2 + 5) + 4 = 11
2 + (5 + 4) = 11
Associative Property of Multiplication correct answers Changing the grouping of three or more
factors does not change the product
(2 x 5) x 4 = 40
2 x (5 x 4) = 40
Identity Property of Multiplication correct answers If you multiply a number by one, the product
is the same as that number
3x1=3
base ten blocks correct answers These are plastic cubes, rods, flats, and blocks used to teach
place value.
