Cheat Sheet
- Understanding the Number Line Method -
The number line is a visual tool that helps you add and subtract integers by moving right for positive steps and left for negative steps (source: Khan Academy). For example, starting at -3 and moving 5 steps yields -3 + 5 = 2, making visual tracking a breeze.
- Applying Sign Rules for Integer Addition -
When adding integers with the same sign, add their absolute values and keep the sign (e.g., -4 + -6 = -10); with opposite signs, subtract the smaller absolute value from the larger and take the sign of the larger (e.g., -7 + 2 = -(7 - 2) = -5) (per National Council of Teachers of Mathematics). Mastering these rules is key for success in any integers adding and subtracting quiz.
- Rewriting Subtraction as Addition -
Transform any subtraction problem into addition by adding the opposite: a - b becomes a + (-b), so 4 - (-3) becomes 4 + 3 = 7 (as noted in UC Berkeley's math notes). This strategy helps simplify subtraction and is often featured in addition and subtraction of integers quizzes.
- Leveraging Absolute Value to Compare Magnitudes -
Use the absolute value |n| to measure an integer's distance from zero, so | - 8| = 8 and |5| = 5 when deciding which integer has greater magnitude (according to the University of Cambridge). In problems like -9 + 4, compare |9| and |4|, subtract to get 5, then assign the sign of the larger absolute value for quick mental math.
- Utilizing Associative and Commutative Properties -
Group and reorder terms to simplify multi-step problems, since addition of integers is both associative and commutative (e.g., (-3 + 7) + (-2) = (-3 + -2) + 7 = 2) (per MIT OpenCourseWare materials). Rearranging terms can speed up your calculations and boost confidence on your adding and subtracting integers test.
