This calculator can only answer up to 4 digit questions like: 42+34 3-56 5*4 54/9 but cant answer: 123+43 (that has 5 digits) or 1*100 (thats in the hundreds) (There is easter egg!)
And just in case you did not know: +=Add -=Subtract *=Multiply /=Division IMPORTENT: You must not have spaces in ur sum like 2 + 5 Also dont try stuff like 23+2-7 (this is only basic)
