Didnt see the previous thread but im guessing it goes.....

22/2 = 11

(22+2+2)/2 = 13

and er...... B*llocks

Scooby_Loo

22/2 + (2x2)x2= 19.

Think thats how you're meant to write it

Scooby_Loo

hmmmm, thats 6 2s. Unless you count 22 as one

DocJock

22-2-(2/2)=19

PS thanks BTW for solutions to 11,13 and 19

Long division is easy when you know the secret.

Step 1. - Find calculator.


The bit of maths that always confused me was trig calculus. I could never figure out how it worked or why anyone needed to know about the rate of change of the rate of change of arctan. WTF if arctan anyway
