Count Up: Math Game

Reach the target total using the available number tiles and operators to create a running total. Find multiple solutions to unlock all achievements.
Improve your mental arithmetic and mathematics including division and multiplication.

*** How To Play ***
Try to reach the target (above the grid) using some or all of the available numbers and operators. Note that it's a running total so 4 + 5 x 6 is effectively (4 + 5) x 6.
Achievements can be unlocked each time the target is reached. You can then reset the grid and aim to unlock more.
Your solutions will be saved so you can come back later.
