Solving the Age Problem: A Step-by-Step Approach

To solve the first part of the problem, which asks how old Aliya's mom was last year, we perform a subtraction operation. We take her current age, 49 years, and subtract 1 year. This gives us the equation: 49 - 1 = 48. Therefore, Aliya's mom was 48 years old last year. This step highlights the use of subtraction in calculating past ages. For the second part of the problem, which asks how old Aliya's mom will be next year, we perform an addition operation. We take her current age, 49 years, and add 1 year. This gives us the equation: 49 + 1 = 50. Therefore, Aliya's mom will be 50 years old next year. This step demonstrates the use of addition in calculating future ages. By breaking down the problem into these two simple steps, we can easily find the solutions. This approach not only helps in solving the problem but also reinforces the understanding of basic arithmetic operations. It also illustrates how math can be applied to everyday situations, such as calculating ages. This type of problem-solving approach is crucial for developing critical thinking skills and building confidence in mathematical abilities. It encourages children to break down complex questions into smaller, more manageable steps, making the problem-solving process less daunting and more accessible. By mastering these basic age calculations, children gain a solid foundation for more advanced mathematical concepts and problem-solving scenarios. The ability to apply math to real-world situations is a valuable skill that will benefit them throughout their lives. This exercise also reinforces the importance of careful reading and understanding the question before attempting to solve it.

In summary, solving age-related problems like this one is not just about finding the numerical answer; it's about developing a deeper understanding of time, arithmetic operations, and problem-solving strategies. It's a crucial step in building a strong mathematical foundation and fostering critical thinking skills.

2. Exploring Number Formation

The Two-Digit Number Puzzle: Unleashing Creativity with Digits

Number formation is a fundamental concept in mathematics, and this problem presents a unique twist by limiting the available digits. The challenge is to create a two-digit number using only the digit 5, and the allowance of repeating the digit opens up a specific solution. This exercise encourages children to think creatively within constraints and apply their understanding of place value to form numbers. It's not just about knowing the digits but also understanding how they combine to represent different values. The question challenges the notion that number formation always requires different digits and highlights the importance of understanding the structure of the number system. This type of problem promotes a deeper understanding of numerical concepts and enhances problem-solving skills. To solve this, we need to consider how digits are arranged in a two-digit number. A two-digit number consists of a tens place and a ones place. Since we are allowed to repeat the digit 5, we can place the digit 5 in both the tens place and the ones place. This forms the number 55. Therefore, the two-digit number we can make using only the digit 5 is 55. This solution highlights the significance of place value in number formation. The digit in the tens place represents a multiple of ten, while the digit in the ones place represents a unit value. In the number 55, the 5 in the tens place represents 50, and the 5 in the ones place represents 5. The combination of these two values gives us the number 55. This understanding of place value is crucial for developing a strong foundation in arithmetic and number sense. It allows children to comprehend how numbers are constructed and how different digits contribute to the overall value of a number. Furthermore, this problem encourages creative thinking and problem-solving skills. It challenges the assumption that different digits are always needed to form a number and promotes the exploration of various possibilities within given constraints. By solving this puzzle, children not only reinforce their understanding of number formation but also develop their ability to think outside the box and approach mathematical problems with flexibility and ingenuity. The simplicity of the problem belies its importance in fostering a deeper appreciation for the structure and properties of numbers.

Cracking the Code: The Two-Digit Solution

The problem asks us to create a two-digit number using only the digit 5, and we are allowed to repeat the digit. A two-digit number has two places: a tens place and a ones place. To form the number, we can place the digit 5 in both the tens place and the ones place. This gives us the number 55. Therefore, the solution to this problem is 55. This solution demonstrates the fundamental concept of place value in number formation. The digit in the tens place represents the number of tens, and the digit in the ones place represents the number of ones. In the number 55, the digit 5 in the tens place represents 50, and the digit 5 in the ones place represents 5. Adding these values together, we get 50 + 5 = 55. This exercise reinforces the understanding that the position of a digit in a number determines its value. It also highlights the flexibility of the number system, where a single digit can be used repeatedly to create different numbers. This type of problem is valuable in developing number sense and promoting a deeper understanding of how numbers are constructed. It encourages children to think about the structure of numbers and how digits combine to form larger values. Furthermore, this problem fosters creative problem-solving skills.
