95!- 43 = ____

Answer 1

To subtract \( 95 - 43 \) using base ten units and modeling, follow these steps:

1. Line up the place values:

   • Minuend: \( 95 \) (which consists of \( 9 \) tens and \( 5 \) ones)
   • Subtrahend: \( 43 \) (which consists of \( 4 \) tens and \( 3 \) ones)

2. Model the minuend:

   • Represent \( 95 \) with \( 9 \) tens (90) and \( 5 \) ones (5).

3. Subtract the ones:

   • You start with \( 5 \) ones in \( 95 \).
   • Subtract \( 3 \) ones from \( 5 \): \[ 5 - 3 = 2 \]
   • After subtracting, you have \( 2 \) ones remaining.

4. Subtract the tens:

   • You start with \( 9 \) tens in \( 95 \).
   • Subtract \( 4 \) tens from \( 9 \): \[ 9 - 4 = 5 \]
   • After subtracting, you have \( 5 \) tens remaining.

5. Combine the results:

   • You have \( 5 \) tens and \( 2 \) ones left, which is represented as: \[ 5 \text{ tens} + 2 \text{ ones} = 50 + 2 = 52 \]

Thus, the final result of \( 95 - 43 = 52 \).

So, \( 95 - 43 = 52 \).
