a counting number is like 1,2,3,4,5,6 etc
whole numbers are like 0,1,2,3,4,5 etc
integers are like -4,-3,-2,-1,0,1,2,3,4, etc
rational numbers are number that can be writen in form a/b where a and b are integers and b≠0
irrational numbers can't be written in a/b, they are like pi and stuff
and then we've got real numbers which is irratinoal numbers and rational numbers
so
0.3333333333333333333=1/3, that's a rational number and a real number
