What does Formula -> Lookup & Reference do? - answer Shows all formulas If you type = and then click "Fx" in text box, what happens? - answer It lets you know step by step to inserting a formula What does Formulas -> Trace Precedence do? - answer Lets you look at which cells are referenced in a specific formula What does Formulas -> Trace dependence do? - answer Lets you look at which formula is referenced in another formula How do you remove arrows in an error help? - answer Formulas -> Remove Arrows
How to paste formats - answer Copy cells. Paste -> formats Does paste formats do the same thing as format painter? - answer Yes How to paste solely formulas? - answer Paste -> paste special -> formula How to paste solely values and not formulas - answer paste -> paste special -> values What is paste -> multiply? - answer If you want multiple cells to be multiplied by a single cell, you can use this How to paste multiply? - answer Paste -> Paste Special -> multiply What is paste transpose? - answer Switches rows to columns, vice versa (you have to highlight what you want to be switched) How to paste transpose - answer Paste -> Paste special -> Transpose

Ex: =SUMIFS(H2,I2,"Hank") or =SUMIFS(H2,I2,">200") Whats the difference between SUMIF and SUMIFS? or COUNTIF and COUNTIFS - answer The IFS mean that more than 1 criteria is there. If you try to do more than 1 criteria in an IF (like COUNTIF or SUMIF), it'll bring back an error Should you verify countifs and how would you do so? - answer Yes; by using filter Can you use COUNTIFS to see numbers that are greater than, less than, equal to, or does not equal to? - answer Yes Sign for does not equal to - answer <> How to do various COUNTIFS? - answer =COUNTIF(Range 1, Criteria 1, Range 2, Criteria 2, etc.).
