It seems that you've provided an image with mathematical problems. Let me extract the expressions and their explanations:

Problem 25:

• The expression given is $9 \div 3 \times 2 - 12 \div 9$.
• The result obtained is $106$, but this appears incorrect.

Problem 26:

• The expression is $19 - 5 + 12 = 19 - 16$.
• The result obtained is $1$, and this is correct.

Let's correct the reasoning for Problem 25:

1. First, apply the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division (left to right), Addition and Subtraction (left to right)).

   The correct steps are:

   • $9 \div 3 = 3$
   • $3 \times 2 = 6$
   • $12 \div 9 \approx 1.33$

   Now the expression becomes: $6 - 1.33 = 4.67$

Thus, the correct result should be approximately 4.67, not 106.
