Question

12base five-4base five=??

how do i do this??

Answer 1

the number system you're used to is base 10, 0 1 2 3 4 5 6 7 8 9

base 2 has 2 numbers, 0 and 1

base 5 has 0 1 2 3 4 5

to switch any base to base 10 you operate per digit

the first column is going to be multiplied by 5^0, the second 5^1, and so on, just like in base 10

15 base 10 = 1*10^1 + 1*10^0

Answer 2

sorry 1*10^1 + 5*10^0

Answer 3

and base 5 has 0 1 2 3 4 not 0 1 2 3 4 5, sorry it's late
