Solve the Expression: Finding the Value of 63-44

To find an expression equivalent to $63 - 44$, let's begin by calculating the value:

• Step 1: Subtract the numbers $63 - 44$.

Performing the calculation:
$63 - 44 = 19$

Next, we check which expression from the provided choices also results in 19.
Let's evaluate each option:

• Choice 1: $63 - 43$
  $63 - 43 = 20$ (Not 19)
• Choice 2: $63 - 43 + 1$
  $63 - 43 + 1 = 21$ (Not 19)
• Choice 3: $64 - 44 - 1$
  $64 - 44 = 20$
  Subtracting 1: $20 - 1 = 19$
  This matches our target value.
• Choice 4: $64 - 44 + 1$
  $64 - 44 = 20$
  Adding 1: $20 + 1 = 21$
  (Not 19)

Therefore, the expression equivalent to $63 - 44$ is given by choice 3: $64 - 44 - 1$.
