100,000+4,000+800+5100, comma, 000, plus, 4, comma, 000, plus, 800, plus, 5 in standard form.
8090 [49]

Answer: 109,900,000+4,000+800+5

Step-by-step explanation:

First, let’s add the first four numbers: 100,000 + 4,000 + 800 + 5,100. It equals to 109,900.

Next, after we write 109,900;we write a comma. It’ll look like this: 109,900,

Then, we add 000 after the comma. It is going to be like this: 109,900,000

After that, we add a plus sign: 109,900,000+. We still need to add the 4 and the comma: 109,900,000+4,

Then, we add 000, plus, and 800: 109,900,000+4,000+800. It’ll look like that.

Finally, we need to add the plus and the number 5 to the long equation. It’ll look like this:109,900,000+4,000+800+5.

You’re all done! A little tip is to go in order and not do in whatever order.

Anyways, hope this helped!
