**Today’s Challenge**

One simple rule – multiply two numbers together, then either add or subtract the third number to achieve your target number of **10**. The three numbers used in each calculation must be unique digits from **2-9**.

As an example, one such way of arriving at 10 is by (4×3)–2. Can you find the FIVE other ways of making **10** using this rule?

[Note: (4×3)–2 = 10 and (3×4)–2 = 10 would count as just one way!]

**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 2nd & 4th rows of the playing board contain the following fourteen numbers:

3 8 10 17 28 32 35 44 48 54 55 60 63 64

What is the sum of the multiples of 8?

**Make 25 Challenge**

Can you arrive at 25 by inserting 2, 5, 10 and 20 into the gaps on each line?

- ◯²×◯×◯÷◯ = 25
- ◯+◯+◯÷◯ = 25
- ◯÷◯×(◯–◯) = 25
