Question

to make 77 + 48 easier to solve, lou decides to first add on from 77 to get to the next ten. + 3 + 45 77 80? add on to get to 80. 77 + 3 = 80 now, find the sum. 77 + 48 =77 + (3 + 45) =(77 + 3) + 45 =?

Explanation:

Step1: Calculate \(77 + 3\)

We know from the previous step that \(77 + 3 = 80\).

Step2: Add 45 to the result

Now we take the result from Step 1, which is 80, and add 45 to it. So we calculate \(80 + 45\).
\(80+45 = 125\)

Answer:

125
