Section A: Quick Questions
Q1
A — 5
Q2
B — "7"
Q3
A — 10
Q4
A — "55"
Q5
B — To the right
Section B: Match the Pairs
Q1
5 + 5 → Adds two numbers together to give the number 10.
Q2
"5" + "5" → Joins two pieces of text together to make the text "55".
Q3
Quote marks around a digit turn it into text, so it is no longer a number. → "5"
Q4
A phone number should be stored as text, because you never add phone numbers together. → phone = "0412345678"
Q5
"5" + "5" gives 10 → Quote marks make these text, so they are joined to make "55", not added to make 10.
Q6
A spreadsheet cell holds the text "5", so it lines up on the right like a number. → Text lines up on the left in a spreadsheet. Only numbers line up on the right.
Section C: Definitions
Q1
"5" — Text, not a number. Quote marks turn the digit 5 into text, so 5 + 5 makes 10 but "5" and "5" joined make "55". Phone numbers are text too.Section D: Fill in the Blanks

Q1
D — joined holds the text "55" because a and b are text in quote marks. You cannot subtract from text. The line should just be print(joined).
Q2
D — A phone number is text, so it needs quote marks. Without them the computer treats it as a number and drops the leading 0. It should be phone = "0412345678".
Q3
C — Quote marks make "5" text, so adding them joins them into "55" instead of making 10. The line should be total = x + y to add the numbers.
Q4
B — count is a number, but "5" in quote marks is text. You cannot add a number and text. The line should be total = count + 5.
Q5
C — The & sign joins things together, so it would show 55. To add the numbers and get 10, use A3: =A1+A2.
