SDi: Calculate

Keep your brain sharp with simple math problems.

Calculate the target number using addition, subtraction, multiplication, and division (±10).

How to play:

You have a target number, and six numbers that you can use in calculations.

Calculate the target number using these six numbers (addition, subtraction, multiplication, and division).

If you calculate the target number exactly, you will get 10 points (+10).

You will get less points in calculations ±1 to ±9 different from the target number (+9…+1).

You will not lose points in calculations ±10 different from the target number.

But if the difference is more than ±10, you will lose 10 points (−10).

You can find more detailed explanation about calculation and scoring in the app.

Keep your mathematical skills active and sharp…

Enjoy.
