Why Is Subtracting a Negative Adding? | Adding & Subtracting Integers

Does "minus a negative" make your head spin? In this video you'll learn to add and subtract integers with blue (+) and red (−) chips that annihilate each other when they meet! By the end, you'll solve −3 − (−5) in 10 seconds. In this video you'll learn: ✔ Adding integers with the same signs and with different signs ✔ Zero pairs: the chip trick ✔ Adding on the number line ✔ Subtracting = "taking away debt": why minus a negative is a plus ✔ The shortcut: subtracting is adding the opposite ✔ 3 examples from easy to exam level, the 5 − 8 trap and a 5-second challenge ⏱️ CHAPTERS 0:00 The challenge: −3 − (−5) 0:30 Chips that annihilate 0:52 Adding with the same signs 1:16 Adding with different signs 1:46 Adding on the number line 2:09 Subtracting: taking away debt 2:50 Shortcut: subtracting = adding the opposite 3:15 Example ladder 4:11 The trap: 5 − 8 is not 3 4:35 5-second challenge 5:12 The challenge in 10 seconds 5:44 3-card recap 6:02 Wow fact: the two minus keys ◀️ Previous: PA-02 · Integers on the Number Line ▶️ Next: PA-04 · Multiplying & Dividing Integers 📚 Full playlist: The Workshop · Pre-Algebra 💬 Tell me in the comments: what did you get for the challenge −8 + 3 − (−4)? 👍 If this helped, hit like and subscribe — new visual math every week. 🇪🇸 ¿Prefieres en español? → @AlgebrayTrigonometria #math #integers #negativenumbers #prealgebra #algebra #mathhelp #zeropairs
