Question

to make 48 + 34 easier to solve, lou decides to first add on from 48 to get to the next ten. add on to get to 50. 48 + ? = 50

Explanation:

Step1: Define the problem

We need to find the number that when added to 48 gives 50. Let the unknown number be \( x \), so the equation is \( 48 + x = 50 \).

Step2: Solve for \( x \)

To find \( x \), we subtract 48 from both sides of the equation. Using the subtraction operation, \( x = 50 - 48 \). Calculating \( 50 - 48 \), we get \( x = 2 \).
