Add: \[\mathbf{231}.\mathbf{289}+\mathbf{96}.\mathbf{042}+\mathbf{1}.\mathbf{468}+\mathbf{9}.\mathbf{234}\]

Solution:

\[\begin{align}   & \,\text{231}.\text{289} \\  & \,\,\,\text{96}.0\text{42} \\  & \,\,\,\,\,\,\,\text{1}.\text{468} \\  & +\text{ 9}.\text{234} \\  & \underline{\overline{\text{338}.0\text{33}}} \\ \end{align}\]  

 

 

\[\mathbf{2312}\mathbf{.899 + 604}\mathbf{.2146 + 89}\mathbf{.2342}\]

Solution:

\[\begin{align}   & \,\text{2312}.\text{899}0 \\  & \,\,\,\,\text{6}0\text{4}.\text{2146} \\  & +\text{ }\,\text{89}.\text{2342} \\  & \underline{\overline{\text{3}00\text{6}.\text{3478}}} \\ \end{align}\]
