**Today’s Challenge**

It is possible to use seven 5’s (5, 5, 5, 5, 5, 5 and 5) once each, with the four operations + – × ÷, to make all the target numbers from 1 to 5.

For instance, to arrive at the target numbers **1** and **2**, you can do:

- [(5+5)÷5 – 5÷5] × 5÷5 =
**1** - [(5+5)÷5 – 5÷5] + 5÷5 =
**2**

Your task is to show how to arrive at the other target numbers **3**, **4** and **5**.

**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 5th & 7th rows of the playing board contain the following fourteen numbers:

4 6 7 11 16 21 24 27 30 50 70 77 81 84

What is the product of the two prime numbers listed?
