Word scramble
Unscramble the letters and write each key term on the line.
1
OUTRCNE ← 0
The ← assignment operator stores the value on its right in the variable on its left. Here 0 is stored in Counter. The value must match the variable's data type.
2
PNTUI SAENRW
INPUT followed by a variable name reads a value typed by the user and stores it in that variable. Use one variable per INPUT, and OUTPUT a prompt first.
3
TTPUOU
Displays text or values on screen. Text goes in quotes. Items are separated by commas, e.g. ______ "You have ", Lives, " lives left". Also used for user prompts.
4
VIA(D, B)
Returns the whole-number quotient of a divided by b, discarding the fractional part. For example, DIV(10, 3) returns 3. Both a and b are integers.
5
ADM(O, B)
Returns the remainder when a is divided by b. For example MOD(10, 3) gives 1. MOD(n, 2) = 0 means n is even.
6
DAN RO TNO
Logical operators that combine BOOLEAN conditions: AND needs both true, OR needs at least one true, NOT reverses a condition. Use brackets in complex ones, e.g. Age >= 0 AND Age <= 120.
7
GAE >= 81
A precise condition uses a relational symbol and exact values, like ______. Words such as 'Age is old enough' or 'greater than' are too vague and lose marks.

1OUTRCNE ← 0 → Counter ← 0 — The ← assignment operator stores the value on its right in the variable on its left. Here 0 is stored in Counter. The value must match the variable's data type.
2PNTUI SAENRW → INPUT Answer — INPUT followed by a variable name reads a value typed by the user and stores it in that variable. Use one variable per INPUT, and OUTPUT a prompt first.
3TTPUOU → OUTPUT — Displays text or values on screen. Text goes in quotes. Items are separated by commas, e.g. OUTPUT "You have ", Lives, " lives left". Also used for user prompts.
4VIA(D, B) → DIV(a, b) — Returns the whole-number quotient of a divided by b, discarding the fractional part. For example, DIV(10, 3) returns 3. Both a and b are integers.
5ADM(O, B) → MOD(a, b) — Returns the remainder when a is divided by b. For example MOD(10, 3) gives 1. MOD(n, 2) = 0 means n is even.
6DAN RO TNO → AND OR NOT — Logical operators that combine BOOLEAN conditions: AND needs both true, OR needs at least one true, NOT reverses a condition. Use brackets in complex ones, e.g. Age >= 0 AND Age <= 120.
7GAE >= 81 → Age >= 18 — A precise condition uses a relational symbol and exact values, like Age >= 18. Words such as 'Age is old enough' or 'greater than' are too vague and lose marks.
