DAY 1:

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
