For example, to calculate the square root of 16, you press: Enter
with dots 1-2-3-4-5, 16 “)”. Then, press enter.
Your answer will be given as 4.
8. Exponential
For Exponential you can press “enter” with “dots 1-5.”
For example, to calculate the Exponential of 2, you would press:
Enter with dots 1-5 then 2, followed by the “)” and “enter.” That is,
exp (2) which gives the result 7.3890561.
