5 + 3 equals 8 because combining these two values results in 8. This basic addition fact is essential for building strong arithmetic skills.

Subtracting 4 from 10 gives 6. This subtraction problem reinforces the concept of taking away to find a difference.

Among the numbers given, 9 is the largest. Recognizing the largest number in a set is a fundamental skill in comparing values.

Multiplying 2 by 3 gives 6. This multiplication fact is one of the building blocks for more complex arithmetic operations.

The sequence increases by 2: after 2 comes 4, then 6, and finally 8. Identifying number patterns like this is key to mastering arithmetic progressions.

Adding 12 and 15 gives 27. This problem helps reinforce the ability to accurately add two-digit numbers.

Subtracting 9 from 20 results in 11. This subtraction exercise reinforces basic mental arithmetic and number sense.

Multiplying 4 by 6 results in 24. This problem reinforces familiarity with multiplication tables and quick calculation.

Dividing 18 by 2 gives 9, splitting the number into two equal parts. This reinforces the division concept through a straightforward problem.

First, add 5 and 3 to get 8, then multiply by 2 to obtain 16. This problem emphasizes the correct order of operations in arithmetic calculations.

The first three prime numbers are 2, 3, and 5, which add up to 10. Understanding prime numbers is important for recognizing basic number properties.

Subtracting 7 from 13 results in 6. This reinforces a basic subtraction strategy needed for more complex arithmetic.

Among the numbers provided, 17 is the smallest. Comparing numbers is a fundamental skill that supports overall number sense and arithmetic reasoning.

First multiply 3 by 4 to get 12, then add 2 to arrive at 14. This question highlights the importance of following the correct order of operations.

Dividing 30 by 5 gives 6, which when added to another 6 yields 12. This problem integrates division and addition to test sequential calculation skills.

According to the order of operations, multiply 5 by 2 to get 10, then add 7 to obtain 17, and finally subtract 3 to get 14. This problem requires careful sequencing of steps in a multi-operation expression.

Adding 7 to 18 gives 25. This question tests the ability to determine missing values in a simple equation.

Dividing 32 equally among 4 groups gives 8 per group. This problem applies division to determine the value in each equal subset.

Evaluating each option shows that 8 + 12 equals 20, while the others do not sum to 20. This question reinforces quick addition skills and equation evaluation.

First, compute the expression inside the parentheses: 8 - 3 equals 5. Then subtract 5 from 15 to arrive at 10, illustrating proper use of parentheses in calculations.
