Before I begin, PLEASE bear with me. I'm VERY new at Excel. Only using it a few times in the past. So what I learned then I've forgotten. So, I have Office 2016, and I wish to make a simple spread sheet to track income from multiple sources. I'm looking to do monthly totals for each source then a combined daily total from all sources. And that's what took me too long to do tonight. It was a very simple formula of =sum(number1:number2). But 31 days in August I had to type that out 31 times changing each row number. It's done now, but I'm REALLY want to learn Excel, how could I have done this faster without all the typing?
