How can I Multiply two columns then add them together easily? - excel-2019

I would like to Multiply Column A with Column B. There is data for each column in rows 3-20.
Rather than doing (A3B3)+...(A20B20), is there an easier and more efficient way of doing it?

I actually just figured it out. What I want to do can be accomplished with the SUMPRODUCT forumula.
=SUMPRODUCT(Select Column A Values,Select Column B Values)

Google Sheets: How do I reference cell values with text from another cell?

I want to make a list of, say, grocery items. In one column I have the items, in another column I have the costs. I want to create a list with a subset of the grocery items such that the total price of those items is returned.
I've attached a screenshot with an example to demonstrate. The items are in column A; the costs are in column B. The subset of items I want to purchase is in column D; and I want the total cost returned in column E. I want to be able to add or subtract items from Column D and have the total cost update in column E.
Is there a way to do this with functions or minimal scripting? I've looked at documentation for INDIRECT and HLOOKUP, but I don't know these are the functions that I need, and if I do, I don't know how I need to use them.
Try this
=INDEX(SUM(SUMIF(O2:P8,"="&R2:R5,P2:P8)))
The solution that worked for me was to use VLOOKUP with ARRAYFORMULA:
=SUM(ARRAYFORMULA(IF(ISBLANK(D2:D),,VLOOKUP(D2:D,A:B, 2,))))
try:
=INDEX(SUM(1*IFERROR(VLOOKUP(D2:D; A:B; 2; ))))

Google sheets: How to write a formula that performs a sum from column_x until previous column and apply it to the rest of the columns

I have these two columns:
For the next columns I would to apply this formula:
SUM[all_previous_columns]
I would like to write it once for the third column and apply it for the rest of the columns.
Any idea how to do this?
You mean this?
You should use absolute addressing to first column in the range you want to sum and relative addressing to last column. Then you can drag your formula right as far as you want.
As it just doubles each time, you could also write it as an array formula:
=ArrayFormula((A1+B1)*2^(column(C1:1)-3))

Spreadsheet - I want to append data from one sheet to another, they only have one column that can be used as a reference

I have two sheets that only have one column in common - ID column.
I'd like to compare those two columns and if id's match, to append data into Sheet 1 from the matching row.
I don't know if I'm clear enough so here is what I'm trying to achieve:
I've tried looking for any solution, but it's a bit too specific.
Hopefully someone here can explain how can I achieve this?
If you want an one formula solution then use this in cell D2 of Sheet1:
=arrayformula({iferror(vlookup(A2:A, {Sheet2!A2:A,Sheet2!B2:B},2,false),""),iferror(vlookup(A2:A, {Sheet2!A2:A,Sheet2!C2:C},2,false),""),
iferror(vlookup(A2:A, {Sheet2!A2:A,Sheet2!D2:D},2,false),""),iferror(vlookup(A2:A, {Sheet2!A2:A,Sheet2!E2:E},2,false),"")
})
A better alternative suggested by marikamitsos is this:
=ArrayFormula(IFERROR(VLOOKUP(A2:A,Sheet2!A2:E,{2,3,4,5})))
Try below.
=INDEX(Sheet2!B:B,MATCH(A2,Sheet2!A:A,0))
If you want Vlookup() then use-
=VLOOKUP($A2,Sheet2!$A:$E,COLUMN(B$1))

Excel/Sheets Consecutive Count Based on Two Conditions (function?)

I have a Google Sheet, and I'm trying to see if it's possible to get a consecutive count outputted in a third column based on the values of two other columns.
My columns are:
Column A: Will have a handful of text values that are "grouped" together. Likely around 30 of the same value, until it changes to another value. In the image above, these are text1, and text2.
Column B: Will have one of 3 values assigned to each value in column A. In the image above, these are id1, id2, id3.
Column C: Will output a consecutive count based on the values of the first two columns. My hope is that if there are multiple ID1,ID2 in consecutive order, they'll repeat that first +1 value; while ID3 is always plus 1 to the count. This is what I am trying to show in column C in the layout image above.
I've hit a wall with trying to accomplish this with various COUNTIF iterations.
Thanks for any help, or any better ideas to accomplish something similar.
(I'm hoping for a formula, but open to being pointed into a direction for a script if that's the only way).
You can try following formula:
=IF(A2=A1;IF(OR(B2="id3";B2<>B1);C1+1;C1);1)
It is also possible to do this as an array formula. I used offset ranges for column B in the first Countifs to check for a change in value but this made it a little awkward to get equal-sized arrays:
=ArrayFormula(if(A2:A="","",
countifs({"";B2:B}<>{B2:B;""},true,{A2:A;""},A2:A,row(A:A),"<"&row(A2:A),{B2:B;""},"<>id3")+
countifs(A2:A,A2:A,row(A2:A),"<="&row(A2:A),B2:B,"=id3")
))

Google Spreasheet: get unique values from two columns into a single one

I need to get unique values from two columns into a single one.
I tried with formula unique(A:B) but this formula creates two columns for the results. I need the results to be in a single column. Take a look at my capture:
You could try (in D3):
=unique({A3:A;B3:B})
The braces with the semicolon create a stacked column of A and B.
To avoid blanks, you could try:
=filter(unique({A3:A;B3:B}), unique({A3:A;B3:B})>"")
