3. Which comparison gives true?

A 10 < 4

B 4 < 10

4. A comparison like 8 < 5 gives which kind of answer?

A A true or false answer

B A new number

5. What does 6 = 6 check?

B Whether the two values are equal

Match the Pairs

Draw a line connecting each item on the left to its match on the right.

Left column		Right column
17 > 3		AAsks if 2 is less than 9. The answer is true.
22 < 9		BFive is not less than two, so 5 < 2 is false. The greater than symbol > would make it true.
3A comparison with equal to gives false when the two values are different.		C4 = 6
4A program can use a true answer to decide to do something.		Dif score > 10 then show "Pass"
55 < 2 is true		EAsks if 7 is greater than 3. The answer is true.
68 > 8 is true		FEight is not greater than eight because the two values are equal. The comparison gives false.

D // shows false

Question 3

A IF 9 < 6 THEN

B PRINT "9 is bigger"

C END IF

Question 4

A score ← 50

B pass ← score > 40

C IF pass THEN

D PRINT "Try again"

E END IF

Answer Key

Comparing values gives true or false

Section A: Quick Questions

A — true

A — false

B — 4 < 10

A — A true or false answer

B — Whether the two values are equal

Section B: Match the Pairs

7 > 3 → Asks if 7 is greater than 3. The answer is true.

2 < 9 → Asks if 2 is less than 9. The answer is true.

A comparison with equal to gives false when the two values are different. → 4 = 6

A program can use a true answer to decide to do something. → if score > 10 then show "Pass"

5 < 2 is true → Five is not less than two, so 5 < 2 is false. The greater than symbol > would make it true.

8 > 8 is true → Eight is not greater than eight because the two values are equal. The comparison gives false.

Section C: Definitions

7 > 3 — A comparison. Symbols like > (greater than), < (less than) and = (equal to) compare two values and give true or false. 7 > 3 is true, so a program can use it to decide.

Section D: Fill in the Blanks

7 > 3 is true

2 < 9 is true

5 = 5 is true

if score > 10 then
  show "You win"
end if

4 > 9 is false

Section E: Spot the Error

B — 7 < 3 is false, but the program is meant to print true. The comparison should be score > 3, because 7 > 3 is true.

D — 4 is less than 9, so a < b gives true, not false. The comment should say shows true.

A — 9 < 6 is false, so the message would never print. The comparison should be 9 > 6, which is true.

D — 50 > 40 is true, so pass is true and the IF block runs. It should print You pass, not Try again.

C — The variable is called same, so it should check if the two values are equal using =. Using > checks greater than, and 3 > 3 is false.
