Difference between 1 and Real number

1 vs. Real number

1 (one, also called unit, unity, and (multiplicative) identity) is a number, numeral, and glyph. In mathematics, a real number is a value of a continuous quantity that can represent a distance along a line.

Absolute value

In mathematics, the absolute value or modulus of a real number is the non-negative value of without regard to its sign.

Calculus

Calculus (from Latin calculus, literally 'small pebble', used for counting and calculations, as on an abacus), is the mathematical study of continuous change, in the same way that geometry is the study of shape and algebra is the study of generalizations of arithmetic operations.
