R = Real number, almost every number R' = Imaginary numbers, like sqr(-4) because you can't ever multiply two positive numbers to get a negative number Q = Rational numbers, like -3/2, can be expressed in fractions, also includes infinite decimals that are repeating, like 1/7 Q' = Irrational numbers, like Pi ( Repeats forever without any pattern ) Z = Integers, every single number on the number line but not decimals N = Natural numbers, 1 to infinity, no decimals No = Natural numbers but including 0 undefined = anything divided by 0, could also be called infinity

Confusing.
R = Real number, almost every number
R' = Imaginary numbers, like sqr(-4) because you can't ever multiply two positive numbers to get a negative number
Q = Rational numbers, like -3/2, can be expressed in fractions, also includes infinite decimals that are repeating, like 1/7
Q' = Irrational numbers, like Pi ( Repeats forever without any pattern )
Z = Integers, every single number on the number line but not decimals
N = Natural numbers, 1 to infinity, no decimals
No = Natural numbers but including 0
undefined = anything divided by 0, could also be called infinity
Funny i started counting from 0 not from 1 when u sayd to start counting
