Rearrange the number tiles and combine with any
of the four arithmetic operations, +, −,
×, and ÷, so that the value of the
expression you're building is equal to the target number in the
red box below.
Click the spaces between the number tiles until you have the desired
operation. Order of operations will follow the order that you set
the operations, and clicking will undo
the last operation you chose.
When the red box turns green, click it! Yellow means you're close - click it for partial points!
If you've selected the impossible option, clear the operations and then click the red box when you think there isn't a solution. This option requires that you have Same Numbers or Sequential Targets set to On.
A solution can be obtained by clicking the calculator
but it will start a new puzzle and reset your score.
