I thought the "obvious" way to do that 3rd numbers was 75*50/6+6*100/25 = 649. It's essentially a 25 squared method.

The last numbers could also be done an easier way than Rachel's method - (8+4)*3*10+2 = 362. Rachel did 45*8+2, getting the 45 a rather clunky way.

By the way, while I'm here - the other day did they ask whether anyone had ever played their parent/offspring in a game? I wasn't paying that much attention and can't remember what day it was or why it might have come up. But anyway Wayne Summers famously lost to his father in a heat game before going on to win the series and the CoC.

Yeah that's the way I did it too.
Not the biggest numbers faux-pas on today's show though.

Colin asked "A number 1 followed by 100 zeros is known by what name?"
Rachel replied "A googolplex".
The correct answer was a googol. A googolplex is a 1 followed by 10^100 zeros, so slightly out.

If she'd said "four" she would have been closer arithmetically speaking, if not conceptually so.

Yeah. There aren't enough atoms in the universe to even write out that number.

I gave up on 45 * 8 + 2 and did

(10+3)*4*7 + 2
