Algebra 1 | Unit 1 | Lesson 6: Mystery Computations | Practice Problems

What could be the formula used to compute the value shown in cell B3?

• = B3 * B4

• = A2 + A5

• = A2 * A5

• = Sum(A2:A6)

What number will appear in cell B2 when the user presses Enter?

A spreadsheet with rows 1 to 5 and columns A to B. A1 contains “change these”. A2, 10. A3, 5. A4, 0. A5, negative 7. B1, “what happens here?”. B2, “equals sum open parenthesis A3 colon A5 closed parenthesis”. All other cells are blank.

Select all the formulas that could be used to calculate the value in cell B4.

• =Product(A2:A6)

• =Sum(A2:A6)

• = A2 + A3

• = A2 * A3

• = A3 * A4 * A5

The formula in cell B2 is = Product(A2 : A5). Describe a way to change the contents of column A so that the value in cell B2 becomes -70.
