Nine less than five times a number is equal to -30
100% equals the number. Less than 100% is less than the number. Greater than 100% is greater than the number.
3x - 1 = x + 19 2x = 20 x = 10
It means that is is less than or equal to that number.
0
The relational operators are == (equal), != (not equal), < (less than), <= (less than or equal to), > (greater than) and >= (greater than or equal to). All relational operators are boolean, returning true or false depending on the l-value relationship with the r-value, with respect to the operator.
Larger or equal to 0 but less than or equal to 1
