Count on in ones to find the sum. 481 plus six equals what.

In this question, we need to find the sum of two numbers. In other words, we need to add them together. Our first number is a three-digit number. The number’s made up of four 100s, eight 10s, and one one. Our number is 481. And we can find 481 here on our number line. So 481 is the number we’re starting with. And we’re adding a single digit; we’re adding six.

The question tells us to count on in ones to find the sum. We know the number six is made up of six ones. So we need to count in ones six times. So let’s do that, starting with 481, 482, 483, 484, 485, 486, 487. We’ve counted on in ones six times. One, two, three, four, five, six. We started at 481, and we ended at 487. One one plus six ones equals seven ones. So 481 plus six equals 487.
