Question

Find the value of AB base 12 - 45 base 12

Answer 1

To calculate the value of AB base 12 - 45 base 12, we need to perform the subtraction in base 12.

First, let's list the digits in base 12:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B.

Since B is the highest digit in base 12, we need to borrow from the left in the subtraction. We can't subtract 5 from B, so we borrow from the A digit, making it A - 1 = 10 - 1 = 9.

Now, the subtraction becomes:
A - 1 B base 12
- 4 5 base 12

Let's subtract each digit:
A - 4 = 10 - 4 = 6
9 - 5 = 9 - 5 = 4

Therefore, AB base 12 - 45 base 12 is equal to 64 base 12.
