QUESTIONS AND ALL CORRECT
ANSWERS 100% SOLVED AND
GUARANTEED SUCCESS
Whole Numbers ------- ✔ CORRECT ANSWER ✓✓0 and go on forever: 1, 2, 3 and so on. Each
whole number is separated from the next by a quantity of 1
Partial Numbers ------- ✔ CORRECT ANSWER ✓✓Fractions and decimals; not whole numbers
Positive and Negative numbers ------- ✔ CORRECT ANSWER ✓✓a negative number is the
opposite of a positive number, and vice versa.
Integers ------- ✔ CORRECT ANSWER ✓✓All the whole numbers and their opposites. The only
integer that doesn't have an opposite is 0
Absolute Value ------- ✔ CORRECT ANSWER ✓✓an integer's positive distance from 0. It's value
without a negative sign.
Ex: |4| = 4 or |-4| = 4
Working with integers ------- ✔ CORRECT ANSWER ✓✓* Subtracting an integer is the same as
adding its opposite, and adding a number is the same as subtracting its opposite.
, *If an even number of negative integers are multiplied or divided, the product is positive. If an
odd number of negative integers are multiplied or divided, the product is negative.
*To add two integers with the same sign, add their absolute values and give the sum of the sign
that both numbers have
* To add two integers with opposite signs, subtract the smaller absolute value from the greater
absolute value and give the difference the sign of the number with the greater absolute value.
Factor ------- ✔ CORRECT ANSWER ✓✓a factor of a whole number is the whole number that can
be divided into it a whole number of times.
Remember: every whole number has itself and 1 for factors. If those are the only two factors of
a number its a prime number.
Prime number ------- ✔ CORRECT ANSWER ✓✓a whole number that only has itself and 1 for
factors.
Prime factorization ------- ✔ CORRECT ANSWER ✓✓a representation of the number as a product
of all its prime factors.
greatest common factor vs least common multiple ------- ✔ CORRECT ANSWER ✓✓GCF: greatest
factor in common (20: 1, 2, 4, 5, 10, 20)
LCM: lowest number in common and is a multiple instead of a factor. (3: 3, 6, 9, 12...)
Exponent ------- ✔ CORRECT ANSWER ✓✓represents how many times a number is a factor. 2 =
squared, 3 = cubed
Square root ------- ✔ CORRECT ANSWER ✓✓a way to find what has to be squared to get a
number
