What is the meaning of equation: M = ∑mi

[rudy]

Homework Statement

This equation is on a formula sheet for an exam and I'm not sure what type of problem it even applies to.

Homework Equations

M = ∑mi
(The i is supposed to be written as a subscript in this equation)

The Attempt at a Solution

Total mass = sum of individual masses? This seems too obvious. Is this really the answer?

The formula sheet is for an exam on conservation of energy, Newton's laws and momentum / collisions.

Thanks in advance

Without any further context, I would say you are correct -- sum of the individual masses.
