Questions and formulas:
Question: What is average SiO 2, when Na 2 O is 7.53, and when Al 2 O 3 is less than 2.13?
Formula: AVERAGE(FILTER(C1, (G1=7.53)*(D1<2.13)))
Formula2: AVERAGE(FILTER(C2:C7, (G2:G7=7.53)*(D2:D7<2.13)))
Level: easy
Question: What is the highest K 2 O, when Na 2 O is greater than 1.87, when Fe 2 O 3 is greater than 0.07, when Objects is Ritual Disk, and when Al 2 O 3 is less than 0.62?
Formula: MAX(FILTER(F1, (G1>1.87)*(E1>0.07)*(A1="ritual disk")*(D1<0.62)))
Formula2: MAX(FILTER(F2:F7, (G2:G7>1.87)*(E2:E7>0.07)*(A2:A7="ritual disk")*(D2:D7<0.62)))
Level: easy
Question: What is the highest SiO 2, when K 2 O is greater than 0.16, when Fe 2 O 3 is greater than 0.16, and when Na 2 O is less than 7.53?
Formula: MAX(FILTER(C1, (F1>0.16)*(E1>0.16)*(G1<7.53)))
Formula2: MAX(FILTER(C2:C7, (F2:F7>0.16)*(E2:E7>0.16)*(G2:G7<7.53)))
