An expression like 30 + 5 × 4 can be confusing without rules! Let's learn how to read it the correct way, every time.
🧩Terms: The parts of an expression separated by a '+' sign. In 12 + 7, the terms are 12 and 7.
➖Subtraction as a term: 83 − 14 is the same as 83 + (−14). So the terms are 83 and −14.
🔒Brackets first: Always solve what's inside the brackets before anything else.
✖️Multiply/divide before add: In a term like 5 × 4, do the multiplication first — it's a single term, not two.
🔄Commutative & Associative: You can swap or regroup terms being added — the answer stays the same!
🎁Distributive property: 3 × (6 + 7) = 3×6 + 3×7 — multiplying a sum is the same as multiplying each part and adding.
Try thisMallesh has 30 marbles, Arun has 5 bags of 4 marbles. Total = 30 + (5 × 4) = 30 + 20 = 50 marbles
