Let's solve $503 - 278$ step by step! 🎉
**Step 1:** Imagine you have 503 candies 🍬. Let's show 500 candies and 3 candies.
Group 1:
🍬 🍬 🍬 🍬 🍬
(5 groups of 100 candies)
🍬 🍬 🍬 🍬 🍬
(5 groups of 100 candies)
Group 2:
🍬 🍬 🍬
(3 candies)
**Step 2:** Now, we want to take away 278 candies.
**Step 3:** Let's break 278 into 200 + 70 + 8.
**Step 4:** Take away 200 from the 500 candies:
🍬 🍬 🍬
(3 candies)
After taking 200:
🍬 🍬 🍬
(3 groups of 100 left)
**Step 5:** Take away 70 candies. We need to take 7 tens from 0 tens, so we borrow 1 hundred (100 candies) from the 3 hundreds.
Now we have 2 hundreds left and 10 tens.
Take away 7 tens:
🍬 🍬 🍬
(3 groups of 100 left)
After taking 70:
🍬 🍬
(2 hundreds left) 🍬 🍬 🍬
(3 tens left)
**Step 6:** Take away 8 candies from 3 candies. We need to borrow 1 ten (10 candies) from 3 tens, leaving 2 tens and 13 candies.
Now take 8 candies:
🍬 🍬
(2 hundreds left) 🍬 🍬 🍬
(3 tens left)
After taking 8 candies:
🍬 🍬
(2 tens left) 🍬 🍬 🍬 🍬 🍬
(5 candies left)
**Step 7:** Put it all together:
🍬 🍬
(2 tens left) 🍬 🍬 🍬 🍬 🍬
(5 candies left)
Answer:
🍬 🍬
(2 hundreds = 200) 🍬 🍬
(2 tens = 20) 🍬 🍬 🍬 🍬 🍬
(5 candies = 5)
So, $503 - 278 = 225$. Great job! 🎯🍬 🍬
(2 hundreds = 200) 🍬 🍬
