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
