Today’s Challenge
You’re playing Roll3Dice and have rolled the numbers 1, 2 and 4 with your three dice.
Using these once each, with + – × ÷ available, this is a truly unique combination being the only one possible where you can make all ten target numbers from 1-10, as seen below.
Place 1, 2 and 4 into the gaps on each line so all the calculations work out:
- ◯–(◯+◯) = 1
- ◯×◯–◯ = 2
- ◯÷◯+◯ = 3
- ◯×(◯–◯) = 4
- ◯+◯–◯ = 5
- ◯×◯+◯ = 6
- ◯×◯–◯ = 7
- ◯×◯×◯ = 8
- ◯×◯+◯ = 9
- ◯×(◯+◯) = 10
