Question

Evaluate the following:
36.36 − 28.4237 − 9.78 + 7.7

Answer 1

36.36 − 28.4237 − 9.78 + 7.7
= 36.36 + 7.7 − (28.4237 + 9.78)

$$\begin{gathered} \stackrel{1}{3}\stackrel{1}{6}.36 \\ \underline{+7.70} \\ \underline{44.06} \end{gathered}$$ $$\begin{gathered} \stackrel{1}{2}\stackrel{1}{8}.\stackrel{1}{4}237 \\ \underline{+9.7800} \\ \underline{38.2037} \end{gathered}$$

= 44.06 − 38.2037

$$\begin{gathered} \stackrel{3}{\cancel{4}}\stackrel{13}{\cancel{4}}.\stackrel{10}{\cancel{0}}\stackrel{5}{\cancel{6}}\stackrel{9}{\cancel{0}}\stackrel{10}{\cancel{0}} \\ \underline{-38.2037} \\ \underline{05.8563} \end{gathered}$$

= 5.8563
