My First Math ? + and -

My First Math ? + and - is simple, clean and easy to use application for practicing of addition and subtraction exercises for first grade students and everyone, who would like to tease their brain with a little bit of math. This version of our popular application in the series rises the bar by changing of the missing part of the exercise. The missing part is either one of the operands or the result itself.

- Main functions:
-- Setting of a maximum number used by the exercise generator between 0-999. (Affects both operands and the result.)
-- Tracking number of processed exercises during the session.
-- Tracking number of correct and wrong answers during the session.
-- Tracking number of exercises, where the student calculated the answer with the opposite operator (plus instead of minus and vice versa). In such case the operator is also highlighted, which helps the student recognize the situation and improve the focus.
-- The varying of the missing exercise part - either one of the operands or the result part - is making the exercises more difficult and more fun for the young mathematicians.
