Test your mental agility with this Mental Arithemetic Time Trial Quiz.
Are you a book worm when it comes to Science quizzes? Do you know "4 - 3 x 20 ="
If so why not play our Mental Arithmetic quiz and see how you compare to other members on our Mental Arithmetic leaderboard. If questions like:
"100 ÷ 20 x 6 ="
or
"159 - 24 = "
seem a little tough then maybe try a different quiz, but remember, even if you don't rank in the top 20, you can still bank your prize entries! Good luck!
