3x2 +3x2
What is 3x2 +3x2 . (You cannot add these terms since they are not the same.)
100
The only number which is a Whole number but not a Counting (Natural) number
What is 0 (zero)?
100
A card is drawn randomly from a standard deck of 52 cards. The probability of drawing a red card.
What is 0.5?
100
If a = b and b = c then a = c
What is transitive property
100
A number 0 such that a + 0 = a and 0 + a = a
What is additive identity
200
7x2 +3x2
What is 10x2
200
The number group that has pi as an element.
What is Irrational Numbers?
200
If you have an equal chance of choosing any integer from 1 to 20 (inclusive), the probability that the number chosen is less than 7.
What is 0.3?
200
a(b + c) = ab + ac
What is distributive property
200
The product of a number and a variable - for example the expression 3x.
What is " a term".
300
3a2b + 4a3 +b2
What is 3a2b + 4a3 +b2 (You cannot add these terms sine the exponents are different.)
300
All the number groups that have 0.5 as an element.
What are Real Numbers and Rational Numbers
300
A jar contains 2 red marbles, 3 blue marbles and 1 green marble. The probability of randomly drawing a red or a blue marble
What is 5/6?
300
If a + c = c + a
What is commutative property
300
In a function, the variable whose value is subject to choice - the input.
What is the domain
400
4(2x-5) - 3(x-2)
What is 5x-14
400
A decimal that is non-repeating and non-terminating
What is an Irrational Number?
400
A jar contains 2 red marbles, 3 blue marbles and 1 green marble. The probability of randomly drawing a red marble (holding on to it) AND then drawing a blue marble
What is 1/5? The probability of drawing the red marble was 2/6 and the probability of drawing the blue marble was 3/5
400
Are integers closed under division. (Give an example to support your answer)
No, integers are not closed under division because 1 divided by 2 is a fraction and fractions are not integers
400
Terms that have the exact same variable(s) raised to the same exponents.
What are "like terms"
500
-5(2x + 4y - 3z) - 3(-6x +7z)
What is 8x - 20y - 6z
500
A number that is an Integer but not a member of the Whole Number set.
What is a negative number?
500
Let a @ b be defined as (a+b)/b. Is the operation @ closed for real numbers? Give an example.
No, @ is not closed because if "a" was any real number and b = 0, then a@b would not yield a real number since no real number can have a denominator of zero.
500
The value(s) of a variable that make an equation or inequality true
What is "the solution"
