264 + 7 = 271

So the number that is 7 more than 264 is 271.

Explanation: Here, we can start by adding 7 to 264 to get 271.

Step 1b

Here’s a number line that shows the steps:

0 10 … 250 260 264 265 266 267 268 269 270 271

We start at 264 on the number line and then add 1 seven times to get to 271.

Each tick mark on the number line represents one unit.

Explanation: Here, we are using the number lines which is 7 more than 264. Then we get 271.

Identify the number line to add 24 + 33 = _.

Step 2b

Here’s a number line that can help you visualize the addition: 0 10 … 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 …

Explanation: Here, we have a number line that can assist you in visualizing addition.

Step 2c

We start at 24 on the number line and then add 33 more units by moving to the right.

We can count each unit as we move along the number line, and the final result

is the number we land after we add all the units.

So, 24 + 33 = 57.

Explanation: Here, we are using the number lines for the given numbers and then adding the values. Finally, we get 57.
