Answer 2

Sure, I'll solve each of these mathematical expressions step by step using the standard written method.

a) $82,72 + 513,9 + 7,346$:

$$\begin{align*} &\quad\phantom{0}82.72 \\ &+ \phantom{0}513.9 \\ &+ \phantom{0}7.346 \\ \hline &\phantom{0}604.966 \\ \end{align*}$$

b) $3,47 + 2,739$:

$$\begin{align*} &\quad\phantom{0}3.47 \\ &+ \phantom{0}2.739 \\ \hline &\phantom{0}6.209 \\ \end{align*}$$

c) $1,55 + 6,8 - 0,7242$:

$$\begin{align*} &\quad\phantom{0}1.55 \\ &+ \phantom{0}6.8 \\ &- \phantom{0}0.7242 \\ \hline &\phantom{0}7.6258 \\ \end{align*}$$

d) $39,5 - 7,52 + 10,087$:

$$\begin{align*} &\quad\phantom{0}39.5 \\ &- \phantom{0}7.52 \\ &+ \phantom{0}10.087 \\ \hline &\phantom{0}41.067 \\ \end{align*}$$
