WebNov 24, 2015 · You can see $7$ is farther to the right than $-5$, so $7 > -5$. Multiply both of those values by $-1$, and you flip the number line: $<--- (-7) ----- 0 ---- (5) ----->$ Now you can see $5$ is farther to the right than $-7$, so $5 > -7$, or $-7 < 5$. You can extend that logic to an equation with variables, like the example in the question: $-5m>25$ data mapping vs data dictionary
