First, rewrite the expression clearly by removing the parentheses, remembering to distribute the minus sign across the second group: \((6m^{4} - 3m^{2} + m) - (2m^{3} + 5m^{2} + 4m) + (m^{2} - m)\) becomes \(6m^{4} - 3m^{2} + m - 2m^{3} - 5m^{2} - 4m + m^{2} - m\).
Next, group like terms together. Like terms are terms that have the same variable raised to the same power. Grouping gives: \(6m^{4} + (-2m^{3}) + (-3m^{2} - 5m^{2} + m^{2}) + (m - 4m - m)\).
Now, combine the coefficients of each group of like terms by adding or subtracting them: For \(m^{4}\) terms: \$6m^{4}$; for $m^{3}\( terms: \)-2m^{3}$; for $m^{2}\( terms: \)-3 - 5 + 1$; for $m$ terms: \(1 - 4 - 1\).
Simplify each group by performing the arithmetic on the coefficients: Calculate the sum for \(m^{2}\) terms and for \(m\) terms separately.
Finally, write the simplified expression by combining all the simplified terms back together, maintaining the order from highest to lowest power.
