You can do almost any operation with this calculator like: addition,subtraction,multiplication,division,cos,tan, atan,Square root,floor,ceiling,abs,asin,acos,log,In,e^,10^ and maybe other things too. 150+ blocks!!! (152 to be precise) Please like and favorite!!! Also follow me! It may ask you the same question twice. Also please use capital for the first letter of the operations name or it might not work i do not know. comment if there are glitches plus it is being worked on. And when it says first number it means the first whole section like 1234 not the literal first number like 1, same thing with second number which it only asks for 2 number questions.
