Do not go to the next calculation before you have finished the previous one..
You do not ever need to write or remember the answers, just do it using your mind.
You'll be surprised.
Start:
How much is:
15 + 6
3 + 56
89 + 2
12 + 53
75 + 26
25 + 52

I know! Calculations are hard work, but it's nearly over..
Come on, one more...

QUICK! THINK ABOUT A COLOR AND A TOOL!
Scroll further to the bottom...
