Final answer:
Without additional context, we cannot determine the sum of m24, m25, and m26. The variable 'm' needs to be defined within a specific context or provided with additional details.
Step-by-step explanation:
The question seems to be asking for the sum of three mathematical expressions: m24, m25, and m26. However, without additional context or information about what m24, m25, and m26 represent, it is not possible to provide a definitive answer. If 'm' indicates a magnification or multiple, and 24, 25, and 26 are the multipliers, then we simply add those values together. Nonetheless, the typical interpretation in mathematics for 'm' followed by a number is undefined unless specified within a specific context or problem statement. Therefore, based on the information provided, we cannot answer what m24 + m25 + m26 is without further details.
