mathematics. exponential function, in mathematics, a relation of the form y = a^x, with the independent variable x ranging over the entire real number line as the exponent of a positive number a. Probably the most important of the exponential functions is y = e^x, sometimes written y = exp (x), in which e (2.7182818…)

The original xtramath guy had a special place in everyone's hearts. But unfortunately, he has been replaced by an animated version. This new animated version has less of the joy and liveliness of the original. It is estimated that 6.5 Million students use XtraMath annually.

That starting value ex will multiply eX in the additional part. So ex times eX must be the same as exCX : This is a “differential equations proof” that the exponents are added.

An operation is complete when the student has demonstrated fluency in all the individual facts within the operation. When this is the case, the fluency matrix on their student report will be completely green, and the score will be 100. Fluency score: 100 (done with the operation!)
