Convert 101001two to base ten? Anyone Anyone?

well, you've probably been taught how to do this.

You need to write it out with your powers of 2 above your number, then add up the powers of 2 that have a 1 below it

so, an example, 10001101
would be:

128 64 32 16 8 4 2 1
..1...0...0..0..1 1 0 1

so that's 1+4+8+128 = 141

Now you do yours...
