Compute. \[ \begin{array}{r}-6.544-2.78=\square \\ 16.37+(-29.786)=\square\end{array} \]

To solve the two calculations, let's break them down one by one. 1. For the first calculation: \[ -6.544 - 2.78 \] This can be rewritten by adding the negative of the second number: \[ -6.544 - 2.78 = -6.544 + (-2.78) = -9.324 \] 2. For the second calculation: \[ 16.37 + (-29.786) \] This can also be rewritten by adding the negative: \[ 16.37 - 29.786 \] Now performing the calculation: Calculating \(16.37 - 29.786\): \[ 16.37 - 29.786 = -13.416 \] Putting it all together, the final results are: \[ \begin{array}{r} -6.544-2.78=-9.324 \\ 16.37+(-29.786)=-13.416 \end{array} \]
