Multiplication
- To do 17x15 in head, do (15+2)x15 = 15x15 + 15x2 = 255 (becomes easier)
Logarithm
- See Logarithm
- Exponent of a +ve number with irrational exp
- NSOD
- \(a^b = exp(b\ln(a)) = e^{\ln a^{b}} = e^{b\ln a}\)
- This apparently works for other bases like 10 also instead of \e.
Series
Gauss formula
