AND and OR functions in Google Sheets - Cheat Sheet & Quick Revision

Recall & Review

beginner

What does the AND function do in Google Sheets?

The AND function checks if all given conditions are TRUE. It returns TRUE only if every condition is TRUE; otherwise, it returns FALSE.

beginner

What is the result of OR(TRUE, FALSE, FALSE) in Google Sheets?

The OR function returns TRUE if at least one condition is TRUE. Since one condition is TRUE here, the result is TRUE.

beginner

Write a formula using AND to check if A1 is greater than 10 and B1 is less than 5.

The formula is =AND(A1>10, B1<5). It returns TRUE only if both conditions are true.

beginner

How does the OR function behave if all conditions are FALSE?

If all conditions are FALSE, the OR function returns FALSE because it needs at least one TRUE to return TRUE.

intermediate

Can AND and OR functions be combined in one formula? Give a simple example.

Yes! For example, =AND(A1>5, OR(B1=10, C1=20)) checks if A1 is greater than 5 AND either B1 equals 10 OR C1 equals 20.

What does =AND(TRUE, FALSE, TRUE) return?

A TRUE

B FALSE

C Error

D 0

AND returns TRUE only if all inputs are TRUE. Here, one is FALSE, so the result is FALSE.

Which formula returns TRUE if at least one condition is TRUE?

A =OR(A1>5, B1<10)

B =AND(A1>5, B1<10)

C =NOT(A1>5)

D =SUM(A1, B1)

OR returns TRUE if any condition is TRUE.

What will =OR(FALSE, FALSE, FALSE) return?

A TRUE

B 0

C FALSE

D Error

OR returns FALSE if all conditions are FALSE.

How do you check if both A1 and B1 are greater than 0?

A =SUM(A1>0, B1>0)

B =OR(A1>0, B1>0)

C =NOT(A1>0)

D =AND(A1>0, B1>0)

AND checks if all conditions are TRUE.

Which formula checks if A1 is greater than 10 OR B1 is less than 5?

A =OR(A1>10, B1<5)

B =AND(A1>10, NOT(B1<5))

C =AND(A1>10, B1<5)

D =OR(A1<10, B1>5)

OR returns TRUE if either condition is TRUE.

Explain how the AND function works and give a real-life example where you might use it in a spreadsheet.

Think about situations where everything must be true to succeed.

Describe the difference between AND and OR functions and when you would use each.

Consider the difference between 'all must be true' and 'any can be true'.

Practice

1. What does the AND function do in Google Sheets?

easy

A. Returns TRUE only if all conditions are TRUE

B. Returns TRUE if at least one condition is TRUE

C. Returns FALSE if all conditions are TRUE

D. Returns the sum of all conditions

Solution

1. Step 1: Understand the purpose of AND

   The AND function checks multiple conditions and returns TRUE only if every condition is TRUE.

2. Step 2: Compare with other options

   Returns TRUE if at least one condition is TRUE describes OR, C and D are incorrect because AND does not return FALSE if all are TRUE or sum values.

3. Final Answer:

   Returns TRUE only if all conditions are TRUE -> Option A

4. Quick Check:

   AND means all TRUE = TRUE [OK]

Hint: AND needs all TRUE to return TRUE, else FALSE [OK]

Common Mistakes:

• Confusing AND with OR
• Thinking AND sums values
• Assuming AND returns TRUE if any condition is TRUE

2. Which of these is the correct syntax for the OR function in Google Sheets?

easy

A. =OR(A1>5, B1<10)

B. =OR(A1>5; B1<10)

C. =OR{A1>5, B1<10}

D. =OR[A1>5, B1<10]

Solution

1. Step 1: Recall correct function syntax

   Google Sheets uses commas to separate arguments inside parentheses for functions like OR.

2. Step 2: Check each option

   =OR(A1>5, B1<10) uses commas and parentheses correctly. Options A, B, and D use wrong separators or brackets.

3. Final Answer:

   =OR(A1>5, B1<10) -> Option A

4. Quick Check:

   OR uses commas inside parentheses [OK]

Hint: Use commas inside parentheses for function arguments [OK]

Common Mistakes:

• Using semicolons instead of commas
• Using curly or square brackets
• Missing parentheses

3. Given the values: A1=7, B1=3, C1=10, what is the result of =AND(A1>5, OR(B1>5, C1=10))?

medium

A. 0

B. FALSE

C. Error

D. TRUE

Solution

1. Step 1: Evaluate inner OR function

   OR(B1>5, C1=10) means OR(3>5, 10=10) -> OR(FALSE, TRUE) -> TRUE.

2. Step 2: Evaluate AND function

   AND(A1>5, TRUE) means AND(7>5, TRUE) -> AND(TRUE, TRUE) -> TRUE.

3. Final Answer:

   TRUE -> Option D

4. Quick Check:

   AND with all TRUE returns TRUE [OK]

Hint: Evaluate OR inside AND first, then combine results [OK]

Common Mistakes:

• Evaluating AND before OR
• Confusing TRUE and FALSE values
• Assuming numeric values instead of logical

4. Identify the error in this formula: =AND(A1>5 OR B1<10)

medium

A. Parentheses are not needed

B. OR cannot be used inside AND

C. Missing comma between conditions inside AND

D. No error, formula is correct

Solution

1. Step 1: Analyze formula structure

   The formula tries to combine conditions inside AND but misses a comma between A1>5 and OR B1<10.

2. Step 2: Correct syntax for nested functions

   AND requires each condition separated by commas. The correct form is =AND(A1>5, OR(B1<10)).

3. Final Answer:

   Missing comma between conditions inside AND -> Option C

4. Quick Check:

   Separate conditions with commas in AND [OK]

Hint: Use commas to separate all conditions inside AND [OK]

Common Mistakes:

• Omitting commas between arguments
• Thinking OR can't be nested inside AND
• Ignoring parentheses placement

5. You want to check if a student passed both Math and English (score ≥ 50) or scored above 90 in Science. Which formula correctly returns TRUE if either condition is met?

hard

A. =OR(Math>=50, English>=50, Science>90)

B. =OR(AND(Math>=50, English>=50), Science>90)

C. =AND(Math>=50, English>=50, Science>90)

D. =AND(OR(Math>=50, English>=50), Science>90)

Solution

1. Step 1: Understand conditions

   The student passes if both Math and English scores are at least 50 (AND condition) OR if Science score is above 90.

2. Step 2: Translate to formula

   Use AND(Math>=50, English>=50) for both passing, then OR with Science>90 to allow either condition.

3. Final Answer:

   =OR(AND(Math>=50, English>=50), Science>90) -> Option B

4. Quick Check:

   Use OR for either condition, AND for both subjects [OK]

Hint: Use AND inside OR to combine conditions correctly [OK]

Common Mistakes:

• Mixing AND and OR order incorrectly
• Using AND for all conditions instead of OR
• Not grouping conditions properly
