Question

compute.
-4.368 - 3.86 =
14.25 + (-27.381) =

Explanation:

Step1: Compute \(-4.368 - 3.86\)

Subtracting a positive number from a negative number is like adding their absolute values and keeping the negative sign. So, \(\vert -4.368\vert = 4.368\) and \(\vert 3.86\vert = 3.86\). Adding them: \(4.368 + 3.86 = 8.228\). So, \(-4.368 - 3.86 = -8.228\).

Step2: Compute \(14.25 + (-27.381)\)

Adding a negative number is the same as subtracting its absolute value. So, \(14.25 - 27.381\). Since \(27.381 > 14.25\), the result will be negative. Subtract: \(27.381 - 14.25 = 13.131\). So, \(14.25 + (-27.381) = -13.131\).

Answer:

\(-4.368 - 3.86 = \boldsymbol{-8.228}\)
\(14.25 + (-27.381) = \boldsymbol{-13.131}\)
