Explain one way to add 3 digit numbers

1 answer:

4 0

You can add them like this:

so if 156 + 213 + 109 was the equation then you would

first put them in order from biggest to smallest

213
156
+109
-----------

then add:

¹ ← ←
213 ↑
156 ↑
+109 ↑
---------↑ ( carry the 10 )
478 (add the ¹ )

then you get the answer 478!

hope that helps :)

<h3>What are cards?</h3>

The cards are 52 in number in which 13 cards are different. Each card is four in quantity.

Ryan is playing a multiplication game with a pile of 26 cards, each with a number on them.

Each turn, he flips over two of the cards and has to multiply the numbers.

The number of ways in which two cards can be selected from 26 cards, at the same time. The order of those are important.

= 26 p(2)

= 26 x 25
