This is a truly unique combination being the only one possible where you can make all ten target numbers from 1-10, with + – × ÷ available, as seen below.
Can you insert 1, 2 and 4 into the gaps on each line so all the calculations work out?
- ◯–(◯+◯) = 1
- ◯×◯–◯ = 2
- ◯÷◯+◯ = 3
- ◯×(◯–◯) = 4
- ◯+◯–◯ = 5
- ◯×◯+◯ = 6
- ◯×◯–◯ = 7
- ◯×◯×◯ = 8
