Question

What's a unit digit?

Answer 1

the units digit is the rightmost digit of the number. For example for the number 327,
7 is the units digit and means 7 units i.e. 7 ones, giving a total of 7
2 is the tens digit and means 2 tens, giving a total of 20
3 is the hundreds digit and means 3 hundreds, giving a total of 300

so if the rightmost (i.e. units) digit of a number is even, then the number is divisible by 2
