Given numbers are 100, 75, 9, 8, 7, 6 and you can use ( * / + -) brackets, multiply, divide add and subtract. You do not have to use all the numbers.

Target Number Puzzle Game Challenge

Challengingly there are five levels for you to play so you can chart your progress as you improve and move through the levels.
As you would expect Level one is a simple way to start but you must achieve a certain percentage to advance to the next level. However If you are feeling confident you can start at a more advance level. Basically this app improves your mental arithmetic and problem solving skills.
There are daily challenges and a leader board so you can match your skills against others all around the world.
Stimulating your brain with this mental challenge keeps you ahead of the game. Knowing your tables and remembering things you were taught at school will help. You need to know the order of mathematical operations (BODMAS or PEMDAS) but we have a crash course to help you remember this.

Questions about Number Scramble – Mental Math

What game lets me make a target from six numbers?

Number Scramble – Mental Math gives you six numbers and a target. Combine the supplied numbers using arithmetic and brackets. You do not have to use every number.

Can you show an example of a target-number puzzle?

With 100, 75, 9, 8, 7 and 6, one way to reach 961 is (100 × 9) + 75 − 8 − 6 = 961. The 7 is not needed. The order of operations matters when entering the calculation.

Is this the same as the full Countdown game app?

No. This is AppMum’s standalone number-puzzle app, previously described here as Countdown Numbers. The separate Letters and Numbers Countdown app also includes word and conundrum rounds.
