Arithmetics by mickstarify - Arithmetics is a fast paced Math workout, it repeatedly asks you simple customizable arithmetic math questions like 2+2 or 14*17 with variable difficulty. Arithmetics was designed to be fully customizable and allows you to flash the screen green/red if you get a question right/wrong. It can also play a sound (Buzzer and pling noise). Arithmetics allows you to choose which operators to ask, so you can disable subtraction, division and multiplication and only use addition if you like. Arithmetics also allows you vary the difficulty of the questions by allowing you to change the highest number that can be asked. e.g you can change addition's highest number to 1000 and get questions like 343+784 Also PS. The screenshots look a bit jittery around the timer area because its quite hard to take a picture of moving text, so imagine a timer there. And also if you've downloaded the app, could you please give me a rating. Thanks. Recent changes: Improved Efficiency and battery performance.
