Ruby Numbers Operations |
In Ruby you can perform all standard math operations on numbers, including: addition +
, subtraction -
, multiplication *
, division /
, find remainders %
, and work with exponents **
.
Addition:
- Numbers can be added together using the
+
operator.15 + 25 #=> 40
Subtraction:
- Numbers can be subtracted from one another using the
-
operator.25 - 15 #=> 10
Multiplication:
- Numbers can be multiplied together using the
*
operator.10 * 5 #=> 50
Division:
- Numbers can be divided by one another using the
/
operator.10 / 5 #=> 2
Remainders:
- Remainders can be found using the modulus
%
operator.10 % 3 #=> 1 # because the remainder of 10/3 is 1
Exponents:
- Exponents can be calculated using the
**
operator.2 ** 3 #=> 8 # because 2 to the third power, or 2 * 2 * 2 = 8
