In this first introduction to operators, we’ll introduce the operators you are most likely familiar with: arithmetic operators with two operands. Those operators assume the operands are both numbers.

+ performs an arithmetic sum:

 1 + 2 //3

Then we have the subtraction operator (-)

4 - 2 //2

The multiplication operator *:

4 * 2 //8

The division operator /:

4 / 2 //2

And the remainder operator:

4 % 2 //0
