what does the dot between number mean?
Answer provided by our tutors
The dot signifies multiplication. An entry '6x' indicates '6' multiplied by 'x' and can also be entered as '6*x' if you wish. To multiply numeric values, as in "2 multiplied by 3', enter '2*3', where the symbol '*' can be entered through 'Shift+8'.
