Problem Section.

This document is a section from the journal "School Science & Mathematics" that allows readers to share and solve mathematical problems. It provides contact information for submitting problems and solutions, as well as a website for accessing solutions to previously published problems. The document features three mathematical problems proposed by different authors. The first problem involves finding positive integers that satisfy a given equation with natural logarithms. The second problem asks to prove that 3 is the largest value of a constant that satisfies a certain inequality. The third problem seeks to find all continuous functions that satisfy a specific equation involving integrals. These problems are presented as challenges for mathematicians to solve.
