Does fx-991cw have sigma notation?

[@TheCalculatorGuide]

The sigma/summation feature is available in the CATALOG.

[@saifhallem1275]

What if we need just the odd numbers

[@wallride2wallride]

For those wondering how to do the same on the new FX-991CW: CATALOG - Func Analysis - Summation(Σ)

[@TheCalculatorGuide]

I'll look into doing a video when I can.

[@shay008]

[@TheCalculatorGuide]

No it's not possible to do sum to infinity as this can't be inputted.
