Competitors to http://buff.ly/2uepYWS are joining forces ; CoCalc overall still much more powerful if you program.

CoCalc Now Supports Implicit Multiplication
July 7, 2017

This I did not know! +Sage Mathematical Software System // +CoCalc DO SUPPORT implicit multiplication.

=+=+=+=+=
It should be noted that implicit multiplication IS NOT supported in SageMathCell.
=+=+=+=+=

You just need to give the command implicit_multiplication(True) at the start of your worksheet/cell. This is a most welcome feature - especially when introducing #CoCalc to high school students.

Example

x(x+3) ====> Invalid Syntax (implied multiplication)
_x*(x+3) ====> Valid Syntax (explicit multiplication)

However, both of these syntax are valid when the mode of the session mode is set to: implicit_multiplication(True)
