Question

Evaluate the following:

(27.076 + 0.55) - (0.004 + 8.08)

Answer 1

$(27.076+0.55)$ can be calculated as follows:
$\begin{array}{cccccccc}\text{Hundreds}& \text{Tens}& \text{Ones}& .& \text{Tenths}& \text{Hundredths}& \text{Thousandths}& \\ & 2& 7& .& 0& 7& 6& \\ +& & 0& .& 5& 5& & \\ & 2& 7& .& 6& 2& 6& \end{array}$

$(0.004+8.08)$ can be calculated as follows:
$\begin{array}{cccccccc}\text{Hundreds}& \text{Tens}& \text{Ones}& .& \text{Tenths}& \text{Hundredths}& \text{Thousandths}& \\ & & 0& .& 0& 0& 4& \\ +& & 8& .& 0& 8& & \\ & & 8& .& 0& 8& 4& \end{array}$

So, $(27.076+0.55)-(0.004+8.08)$ = $27.626-8.084$
Now, $(27.626-8.084)$ can be calculated as:
$\begin{array}{cccccccc}\text{Hundreds}& \text{Tens}& \text{Ones}& .& \text{Tenths}& \text{Hundredths}& \text{Thousandths}& \\ & 2& 7& .& 6& 2& 6& \\ -& & 8& .& 0& 8& 4& \\ & 1& 9& .& 5& 4& 2& \end{array}$

Hence, the answer is $19.542$.
