Simplify the expression: 10s+–2s

Mathematics

Answer:

\huge\boxed{8s}

Step-by-step explanation:

Expression can be broken down into a couple of parts.

  • A term (like 10s, or -2s)
  • The variable (what the unknown value is being represented by, in this case, s)
  • The coefficient (the number next to the variable, showing what to multiply the variable by - in this case, 10 and -2)

When we have multiple terms with the same variable, we can perform operations on them assuming they have the same variable - for example, 5x + 6x = 11x, as 5+6=11.

We can apply the same logic here, however, note that adding a negative is the same as subtracting a positive. For example, 5 + -2 is the same as 5-2.

10 - 2 = 8

Therefore, our final expression is 8s.

Hope this helped!
