Test questions on understanding positive, negative, and zero integers

📚 Quick Study Guide

• 🔢 Integers: Whole numbers (not fractions or decimals) that can be positive, negative, or zero.
• ➕ Positive Integers: Integers greater than zero (e.g., 1, 2, 3, ...). They are located to the right of zero on the number line.
• ➖ Negative Integers: Integers less than zero (e.g., -1, -2, -3, ...). They are located to the left of zero on the number line.
• ⚫ Zero: Neither positive nor negative. It's the neutral integer.
• ⚖️ Number Line: A visual representation of integers, where numbers increase from left to right.
• 💡 Addition Rules:
  • Adding two positive integers results in a positive integer.
  • Adding two negative integers results in a negative integer.
  • Adding a positive and a negative integer: Subtract the smaller absolute value from the larger absolute value. The result has the sign of the integer with the larger absolute value.
• 🧮 Subtraction Rules: Subtracting a number is the same as adding its opposite (e.g., $a - b = a + (-b)$).
