Formula to Include Same Cell in Separate Worksheets

Hi everyone,

I'm doing a research project that involves over 80 worksheets and I was wondering if there is a specific formula to include the same cell but in separate worksheets.

For example, say I need to sum cell A1 in worksheet 1 with A1 in worksheet 2 with A1 in worksheet 3, all the way until worksheet 80. Is there a way I can sum all these cells without individually selecting all 80 cells? Something that basically says sum A1 from worksheet 1 to worksheet 80?

Really appreciate the help. Thanks!
