what does ^ mean?
Thanks Titanium, your answer is good except that you have used the wrong symbol between the 21 and the 3.
The ^ is called a hat or a caret
^ is a symbol representing exponents. for example, if it was 2^2, it would be 2*2, if it were 21*3, it would be 21*21*21
you can use this symbol in the calculator
done! no questions asked.
