Converting from hexadecimal to base 10

a.) Convert (BEAD) base 16 to base 10
b.) Convert (17837) base 10 into hexadecimal/base 16

There should be examples in your book. For the first one, you take B*16^3 + E*16^2 + A*16 + D, remembering that A=10, B=11, etc. For the second, you have to find the powers of 16 that go into 17837, and how many times each goes into it. To start it, you notice that 16^3=4,096, which goes into 17837 four times. If you take the remainder from that division you get 1453, and you then continue with however many times 16^2 goes into that, etc. The hex number you build up will have 4 (the "four times" from my first calculation) in the "16 cubed" position. And you build up the answer like that.

There will be examples in your book/notes...

BEAD hex = 48813 decimal
17837 dec = 45AD hex
