**Today’s Challenge**

Here is a number puzzle similar in concept to my **FlagMath** card game. Many schools are now playing the various editions, so here’s a taster:

Each of the eight letters, A-H, in the two sections contain a calculation with an answer in the 20’s:

- Section 1

B:84÷4 G:29–6 C:35–15 D:14+10 A:5×5 H:72÷3 E:7×4 F:16+11

- Section 2

H:15+12 B:34–8 F:9×3 E:48÷2 C:11×2 G:60÷3 A:17+12 D:40–15

Which is the only letter that has the SAME answer in BOTH sections?

**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 & 2nd columns of the playing board contain the following fourteen numbers:

2 10 13 16 21 22 27 33 45 48 55 56 60 70

How many numbers above become prime numbers when 10 is added to them?

**Make 317 Challenge**

Can you arrive at 317 by inserting 7, 8, 9, 10 and 11 into the gaps below?

(◯×◯×√◯)+(◯×◯) = 317
