Converting a Hex into a decimal

Question

How do you convert 4E₁₆ into a decimal?

Answer 1

Hex and Decimal are not all that different. The way we group decimals is by powers of ten. For example 225 is

(2 * 10^2) + (2 * 10^1) + (5 * 10^0). we can use this same exact process on hex numbers, but instead the numbers are grouped by powers of 16. So 4E would be (4 * 16^1) + (14 * 16^0). If we solve this expression we will finish with the result of 78.
