**Today’s Challenge**

Starting from ONE, what is the 7th whole number, when written in English, that does NOT contain the letter ‘E’?

**The 7puzzle Challenge**

The playing board of **the 7puzzle game** is a 7-by-7 grid containing 49 different numbers, ranging from **2 **up to **84**.

The 1st & 3rd rows of the playing board contain the following fourteen numbers:

2 9 13 14 15 22 25 36 40 42 45 66 72 80

List THREE sets of four different numbers that all have a sum of 200.

**Make 100 Challenge**

Can you arrive at 100 by inserting 4, 5, 8 and 10 into the gaps on each line?

- ◯×◯+◯×◯ = 100
- (◯+◯÷√◯)×◯ = 100
- ◯²×(◯+◯–◯) = 100
- (◯³÷◯)×◯÷◯ = 100
- ◯²×(◯+◯–◯)² = 100
- (◯×◯+◯)×√◯ = 100
- [(◯×◯)÷(◯–◯)]² = 100
