Is missing a denomiator on Divide? I don't get it.

We don't get denominator while using DIVIDE(4,2) gives you 2. It works like this.

Numerator is the first argument i.e. SUM('financials'[Sales])-PREV_QUARTER. Denominator is the second argument i.e. PREV_QUARTER https://learn.microsoft.com/en-us/dax/divide-function-dax

There is a small typo in the DATEADD part, but apart from that the given answer is correct. Here it is typed out for easy reference: Sales QoQ% = IF(ISFILTERED('FACT_Order'[Date]), ERROR("Oh noes"), VAR PREV_QUARTER = CALCULATE(SUM(FACT_Order[OrderID]), DATEADD(FACT_Order[Date], -1, QUARTER)) RETURN DIVIDE(SUM(FACT_Order[OrderID]) - PREV_QUARTER, PREV_QUARTER)) (I used a fact order table to calculate this.)

As for the correctness of the functions used, the measure is Ok, but does this measure count what is required? According to this mesure, current sales are the sum of the contents of the entire table minus the previous quarter. When Q3 is current, we divide the sum of Q1 and Q3 by Q2. Shouldn't it be DIVIDE(Q3,Q2) ?
