💡 Hint

Common Mistakes

Putting TRUE or FALSE directly inside NOT instead of a cell reference.

Leaving the parentheses empty.

The NOT function reverses the logical value. Using A1 inside NOT returns TRUE if A1 is FALSE.

Complete the formula to return TRUE if B2 is NOT equal to 10.

Excel

=NOT(B2 [1] 10)

Drag options to blanks, or click blank then click option'

B<

C=

D<>

💡 Hint

Common Mistakes

Using '<>' instead of '=' inside the formula.

Confusing greater than or less than operators.

The operator '=' checks for equality. NOT reverses the logical test, so NOT(B2=10) returns TRUE if B2 is not equal to 10.

Fix the error in the formula to correctly return TRUE if C3 is NOT TRUE.

Excel

=NOT([1])

Drag options to blanks, or click blank then click option'

AC3=TRUE

BTRUE

CNOT(C3)

DC3

💡 Hint

Common Mistakes

Using 'C3=TRUE' inside NOT causes a logical test that returns TRUE or FALSE, but is redundant.

Nesting NOT inside NOT causes double negation.

NOT(C3) returns TRUE if C3 is FALSE. Writing C3 alone inside NOT is correct.

4fill in blank

hard

Fill both blanks to create a formula that returns TRUE if D4 is NOT blank.

Excel

=NOT(D4 [1] [2])

Drag options to blanks, or click blank then click option'

A=

B<>

C""

D0

Attempts:

💡 Hint

Common Mistakes

Using '<>' with 0 instead of empty quotes.

Forgetting to put quotes around the empty string.

The formula checks if D4 is not equal to an empty string "" (blank). NOT reverses it, so it returns TRUE if D4 is not blank.

5fill in blank

hard

Fill both blanks to create a formula that returns TRUE if E5 is NOT greater than 100.

Excel

=NOT(E5 [1] [2])

Drag options to blanks, or click blank then click option'

A>

B<=

C100

D50

Attempts:

💡 Hint

Common Mistakes

Using '<=' inside the parentheses instead of '>'.

The formula inside NOT checks if E5 is greater than 100. NOT reverses it, so it returns TRUE if E5 is less than or equal to 100.
