Calcul will help your elementary school students practice mental arithmetic or to do fractions. Choose addition, subtraction, multiplication, division or fractions; then set the range of numbers and the number of calculations for an exercise. The program shows you two numbers or fractions respectively, and you enter an answer. Right or wrong answers get audio feedback and there's a pie chart to show your percentage of correct responses. For a greater challenge, play against a friend or set a time limit for a correct answer. The interface and sounds are available in English or German. More languages are supported.
Our Review: Fast and simple way of testing your kid's (or your own!) mental arithmetic skills. With adjustable time allowed and number of players, Calcul makes a great job of testing addition, subtraction, multiplication and division of both whole numbers and fractions. If you're after a real challenge for yourself, try the mixed option under 'stress'. Ouch! The interface is hardly cutting edge but that really won't make a difference as you're struggling for the correct answer. Top freeware and fun for all the family!!
