Work through these flashcards in short sessions. Try to answer each prompt before flipping the card, then revisit any cards you miss until the explanation feels automatic.

Flashcard 1: What integer represents a charge of $3$ units of negative electric charge?

Answer: $-3$. Negative electric charges are represented by negative numbers.

Flashcard 2: A bank account shows a debit of $25. What integer represents this balance change?

Answer: $-25$. Debits represent money owed or withdrawn.

Flashcard 3: What does $0$ mean when using integers to describe a real-world situation?

Answer: $0$ means the reference point or no net change in that context. Zero marks the starting point or neutral position between opposites.

Flashcard 4: What does $0$ mean for elevation measured relative to sea level?

Answer: $0$ means sea level (neither above nor below sea level). Sea level serves as the zero point for measuring elevation.

Flashcard 5: A diver is $8$ meters below sea level. Which integer represents the diver's elevation?

Answer: $-8$. Below sea level positions are represented by negative integers.

Flashcard 6: What is the opposite of $0$ on a number line?

Answer: $0$. Zero is its own opposite; it's neither positive nor negative.

Answer: $0$. Zero degrees is neither positive nor negative temperature.

Flashcard 23: What does $0$ mean when elevation is measured relative to sea level?

Answer: $0$ means sea level (the reference elevation). Sea level is the standard reference point for measuring elevation.

Flashcard 24: Which number represents a credit (deposit) of $40$ dollars?

Answer: $40$. Credits are positive additions to an account balance.

Flashcard 25: Choose the correct description for $0$ meters relative to sea level.

Answer: At sea level. Zero elevation means exactly at the sea level reference point.

Flashcard 26: Which is greater: $-1$ or $-6$?

Answer: $-1$. On a number line, $-1$ is closer to zero than $-6$.

Flashcard 27: A hiker is at $15$ meters elevation. Which integer represents the hiker's elevation?

Answer: $15$. Above sea level positions are represented by positive integers.

Flashcard 28: Which number represents $30$ meters below sea level?

Answer: $-30$. Below sea level elevations are negative values.

Flashcard 29: What integer represents moving $4$ units right from $0$ on a number line?

Answer: $+4$. Moving right from zero gives positive numbers.

Flashcard 30: What does a negative number represent when describing a quantity with opposite directions?

Answer: A value in the opposite direction (below, loss, decrease). Negative numbers show movement or position opposite to the positive direction.

Flashcard 31: A diver is at $-15$ meters and rises to $-9$ meters. What is the change in elevation?

Answer: $+6$ meters. Rising from $-15$ to $-9$ is an increase of $6$ meters.

Flashcard 32: Which number represents a debt of $25$ dollars?

Answer: $-25$. Debts are amounts owed, represented as negative values.

Flashcard 33: Which is less: $2$ or $-2$?

Answer: $-2$. Negative numbers are always less than positive numbers.

Flashcard 34: An elevator is at floor $-2$ and goes up to floor $0$. How many floors does it move?

Answer: $2$ floors. Count the floors between $-2$ and $0$: $-2, -1, 0$.

Flashcard 35: What does $0$ represent in a bank account context using credits and debits?

Answer: $0$ means a zero balance (no money owed and no money owned). Neither owing money nor having money in the account.

Flashcard 36: What does $0$ mean on a temperature scale measured above or below $0$?

Answer: $0$ means neither above nor below $0$; it is the reference point. Zero is the boundary between positive and negative temperatures.

Flashcard 37: What does $0$ mean in a bank account context using credits and debits?

Answer: $0$ means no money in the account; the balance is zero. Zero balance means credits equal debits.

Answer: $+9$. Opposites are the same distance from zero but in opposite directions.

Flashcard 48: In an electric charge context, what does $0$ represent?

Answer: $0$ means neutral (no net electric charge). Equal positive and negative charges cancel out.

Flashcard 49: What does $0$ mean on a temperature scale that uses above and below zero?

Answer: $0$ means neither above nor below zero; it is the reference point. Zero is the boundary between positive and negative temperatures.

Answer: $-7$. Below zero temperatures are negative.

Flashcard 52: What does a positive number represent when describing a quantity with opposite directions?
