Counting Coins & Notes

1

Today's big idea

Count the notes first, then the coins, and add the two parts.

Two ₹20 notes and a ₹5 coin make ₹45.

2

How it works

👀 What's going on?

Indian money comes in coins and notes. Add them to find the total.

💡 Here's the trick

Notes first, then coins₹20₹20₹540+5= ₹45

Count the notes first, then the coins, and add the two parts. Coins are ₹1, ₹2, ₹5 and ₹10; notes are ₹10, ₹20, ₹50 and ₹100.

Two ₹20 notes and one ₹5 coin: 40 + 5 = ₹45.

✍️ Try it

One ₹50 note and two ₹10 coins. How much altogether? → ₹70.

⚠️ Watch out

Add the bigger money first, so you do not lose track.
