Challenge 4-what am i missing?


Am I overthinking this? Did nobody else draw a blank or can’t quite get it like me? Anybody want to shed some light for a newbie?


Post what you’ve tried so far and I can help out!


You can do it! It took me a few tries too.

Challenge 3 was to write out an equation. Challenge 4 actually does the math. Write a function that multiplies your column function and your row function.

Check your punctuation. JS multiplication uses asterisks, not x, and parentheses are important.

Simple is best. I’m sure there’s more than one way to do it, but it’s possible to have only one very short line of code inside the new function.
