How can this be?

10 * 10 + 10 + 10 == 1000

is it because 10 * 10 == 100; 10 + 10 == 100?

multiplying by 8 without using +/-/mult/div is easy using <<
how do you multiply by 7 w/o +/-/mult/div?

I don't how you got this. Try pasting it into google. The answer is 120, as you would expect.

What is that silly "2" thing in 120? It confuses my poor brain that only knows the digits 1 and 0. [img]/images/graemlins/smile.gif[/img]

Next thing you know you'll probably want to introduce me to a crazy "8" digit and claim that
2 * 2 + 2 + 2 = 8.

Oh, I see. You really should have mentioned you were doing binary arithmetic. Who are you hanging out with that this is the assumed base for calculations?

10 = 2
1000 = 8

10*10=4

your original calculation reduces to:

2*2+2+2 = 8

i sense i may still be missing drift. like you wanted some trick internal computer way to do this??

Binary.

correct. How do u multiply by 7 without using the add, subtract, multiply and divide functions?

turbo the man · #7 02-09-2005, 04:39 PM

try using your accumulator
clear acc
acc base
<< base
acc base
<< base
acc base
<< base
acc base
viola, your accumulator is now 7 times what base was originally.
