Count Again

The total number of multiples of 2 that are less than or equal to 100 is \(100\div 2 = 50 \).
The total number of multiples of 5 that are less than or equal to 100 is \(100\div 5 = 20 \).

Is it true that the total number of multiples of 2 and/or multiples of 5 that are less than or equal to 100 is \(50 + 20 = 70 \)?
