That’s a bit annoying Dave… we can’t see all the **complements** to 10 now, we’ll have to imagine that one above the 9, as well as the missing one above the 5…

what can you see?

**complements** to 10 and the **sum** of all the numbers to 10

a nice rectangle 5 x10 + 5 = 55

the old devil **al-jebr** would see:

a half of any number multiplied by the same number plus a half of that particular number is;

**the sum of all numbers up to that number**.

so, add all the numbers up to 100: 50 x 100 + 50 makes 5050 nice…

**the power of al-jebr**

by the way, here’s the same infamous Dave eating Britney:
