Math Safe game

Math Safe is a fun logical thinking game where you need to use the four given single-digit numbers and any of the four operations to reach the target number, and then the safe opens! It practices the usage of all four operations and also the order of operations, because you need to THINK in which order to apply the operations in order to produce the target number. The game suits well grades 4, 5, 6, and onward — adults also will enjoy this game!

For example, maybe you are given 5, 9, 3, and 5, and your target number is 22. You need to perform the operations one at a time, and you can use the answer number in the following operations. For example, you might start with 3 + 9 = 12. At that point, you've used 3 and 9, and you have 12, 5, and 5 left to use. Maybe you next do 5 × 5 = 25. At that point you have 12 and 25 to use — but then it's not possible to reach 22, because none of the four operations, when done with 12 and 25, yield 22 as an answer.


Instructions

You are given four small numbers and a target number. Make number sentences using the given numbers and any of the four operations so that you will reach the target number. At each step, the answer you get becomes a number you can use in subsequent operations.
