Parents and teachers should emphasize Base-10 comprehension in addition and subtraction for children aged 7-9 because this foundational understanding is crucial for mathematical fluency and future learning. At this age, students are beginning to grasp more complex numerical concepts; mastering the Base-10 system—our primary numbering method—ensures they can easily navigate arithmetic operations important both academically and in real-world scenarios.

Firstly, addition and subtraction within the Base-10 system reveal patterns and concepts such as place value, which is the idea that the value of a digit depends on its position within a number. Recognizing that '7' in '70' is actually seven tens rather than just seven primes students for higher mathematical thinking like multiplication and division. For example, deconstructing numbers into tens and ones simplifies processes like carrying and borrowing, which are pivotal for accurate computation in addition and subtraction.

Moreover, a solid grasp of these foundational concepts builds student confidence, reduces math anxiety, and fosters problem-solving skills. It encourages logical thinking, as children begin to see the structure and consistency within numbers. As they grow, this understanding becomes vital for more advanced topics such as fractions, decimals, and algebra.

In essence, a deep comprehension of Base-10 arithmetic is a stepping stone to a lifetime of mathematical literacy and capability, influencing academic success and everyday life problem-solving skills.
