Today’s Challenge
You roll two normal six-sided dice, both containing the numbers 1-6. If you multiplied the two numbers that show, how many DIFFERENT answers is it possible to obtain?
The 7puzzle Challenge
The playing board of the 7puzzle game is a 7-by-7 grid of 49 different numbers, ranging from 2 up to 84.
The 3rd & 7th rows contain the following fourteen numbers:
4 11 13 24 25 27 30 36 42 45 66 70 77 80
What is the sum of the factors of 90?
Make 49 Challenge
Can you arrive at 49 by inserting 1, 2, 3 and 4 into the gaps on each line?
- (◯+◯)²×(◯–◯)² = 49
- (◯+◯)²×√◯–◯ = 49
- ◯⁶–(◯+◯)×◯ = 49
