\( \qquad \) \( 1+2+2+2+2+2+2+2 \)

Did you know that the sum of numbers can be visualized in a fun way? Instead of just adding them up, you can think of them as stacking blocks! If you stack one block, then add two blocks, and repeat adding two blocks six more times, you’ll end up with a total of eleven blocks on top of each other, which is the same as the sum of the sequence. In real life, this kind of addition often appears when you're tracking things like time or resources. For example, if you’re at a pizza party and everyone can eat two slices, if six friends come over, plus the one slice you had earlier - you’d quickly realize you have eleven slices to munch on! So, adding groups together can really help in planning and managing situations.
