Archita | phonics and grammar coach on Instagram: "Adding integers is EASY when you know the rule 👇 ✅ (+) + (+) = + ✅ (+) + (−) = − (bigger number decides) ✅ (−) + (+) = − (bigger number decides) ✅ (−) + (−) = +? ❌ NO! = − ✨ Same signs → Add & keep the sign ✨ Different signs → Subtract & keep the sign of the bigger number 🎯 Quick Challenge: What is ➖7 + ➕3 ?

Most mistakes come from mixing up the rules: when adding integers with different signs, subtract the absolute values and keep the sign of the number with the larger absolute value. When multiplying integers with different signs, the product is negative, and with the same signs, the product is positive. Quick check: do not apply “two negatives make a positive” to addition, that rule applies to multiplication and division #Integers #PreAlgebra #MathTok #MiddleSchoolMath #StudyTips
