For problems 1-5 rewrite the problems vertically (one underneath the other) in your notebook. Then find the sum

Question

0.82 + 4.21

Answer 1

To find the sum of \( 0.82 + 4.21 \), you can write the numbers vertically like this:

  0.82
+ 4.21

Now, let's add them together:

  0.82
+ 4.21
-------
  5.03

So, the sum \( 0.82 + 4.21 = 5.03 \).
