I don’t know what the E is in my calculator. I am calculating 15!* 26! +20.
E is how the calculator expresses overflow by using exponential notation. In most calculators 5E38 would mean 5×10^38.
E stands for exponent. 5 is the base and 38 is power.
15! and 26! are pretty damn big numbers. You calculator can’t display a number that big.
15! = 1,307,674,368,000 26! = 403,291,461,126,605,635,584,000,000
That’s (4×1027)*(1.3×1013).
Good descriptions above. Here are a couple of examples that might make it easy 5E2 is 500 4E4 is 40000 1E0 is 10 3.2E3 is 3200 Get the idea?
500,000,000,000,000,000,000,000,000,000,000,000,000
@CWOTUS You left off the (+20).
