Your calculator just got scrambled! Add up to the target number listed in the goal section. Each round, the numbers on your calculator will change positions. Think carefully: when you select a number, you will only be able to use numbers adjacent to that number!

Click on the button between ADD and MULTIPLY to toggle between the two functions. The word that is lit up is the function you're using. This will help when you need to reach a big number!

Keep going until the timer runs out! The timer is in the bottom left corner of the screen. Each time you reach the goal number, you'll receive few more seconds on the timer.
