Prime Number correct answers A whole number that has exactly two factors, 1 and itself.
Composite Number correct answers A number that has more than two factors.
Rational Number correct answers A number that can be written as a fraction or a decimal,
including repeating decimals.
Irrational Numbers correct answers A number that cannot be written as a fraction or decimal.
Pi is an irrational number, for example.
Absolute Value correct answers The distance a number is from zero on a number line.
0.1, 0.01, 0.001 correct answers Tenths, hundredths, thousandths.
Addition with signs correct answers Take the absolute value of the numbers, perform the
addition and then take the sign of the larger absolute value.
Subtraction with signs correct answers Change the sign of the subtrahend (numbering being
subtracted) and then take the sign of the larger absolute value.
Multiplication with signs correct answers If the signs are the same the product is positive. If
the signs are opposite, the product is negative. If more that two factor are multiplied, then the
sign is determined by how many negative factors are present. An odd amount of negative
factors produce a negative product, an even amount of negative factors produce a positive
product.
Division with signs correct answers If the dividend and the divisor are the same sign it's
positive, if they are opposite it's negative.
PEMDAS "Order of Operations" correct answers The order in which operations should be
done:
- Parentheses
- Exponents
- Multiplication/Division (Preformed left to right)
- Addition/Subtraction (Preformed left to right)
Exponent correct answers A superscript number placed next to another number that indicates
how many times the base number is multiplied by itself.
Roots correct answers Another way of writing a fractional exponent. Nearly all roots you will
encounter will be square roots. Say a is the square root of b, that means a multiplied by itself
is b.
Perfect Square correct answers A number that has an integer for a square root. The 10 perfect
squares from 1-100 are: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100.
