In the big world of numbers, they can be like friends on a playground. Imagine some numbers want to play on the slide, but they're a little short to reach. Their friends can help them by lending a little boost! This fun way of letting numbers help each other is called the 'Friendly Math' way. It's like turning math into a fun game. So, let's play and see how numbers can be best buddies and make adding easier
5638 + 49
Imagine 49 is too shy of having a party for 50. So, 5638, being a kind neighbor, lends 1. This changes our addition to: 5637 + 50 = 5687. Voila! 5638 + 49 is a delightful 5687.
2489 + 29
Here, 29 just needs a little nudge to become a round 30. 2489 steps up and lends that 1: 2488 + 30 = 2518. And just like that: 2489 + 29 turns into a neat 2518.
7056 + 89
89 wants to have a milestone party at 90, just 1 away. 7056 graciously offers that 1:
7055 + 90 = 7145. Magic! 7056 + 89 is transformed to 7145.
373 + 98
98 is eagerly waiting to join the "Three Digit Club" at 100. 373 lends a hand, or rather, a unit: 371 + 100 = 471. Behold: 373 + 98 becomes a cool 471.
8006 + 15
15 dreams of joining the "Twenty League". It's just 5 short! 8006 is generous and lends those 5: 8001 + 20 = 8021. And boom: 8006 + 15 is a sleek 8021.
In Conclusion: Numbers have their own world, and sometimes they just need a little push or pull to make our calculations smoother and more fun. By letting numbers borrow and lend to each other, we make math not just simple, but also more engaging!
