Question

add: 2.134 + 345.04
366.174 366.838
347.174 347.178

Explanation:

Step1: Align decimal points

Write the numbers as \(2.134 + 345.040\) (adding a zero to 345.04 to match decimal places).

Step2: Add column by column

• Ones place: \(2 + 345 = 347\) (wait, no, aligning decimals:
• Units: \(2 + 345 = 347\) (wait, actually, \(2.134\) is 2 units, \(345.04\) is 345 units. Wait, no, decimal alignment:

\(

$$\begin{align*} &\ \ \ \ 2.134\\ +&345.040\\ \hline \end{align*}$$

\)
Adding from right:

• Thousandths: \(4 + 0 = 4\)
• Hundredths: \(3 + 4 = 7\)
• Tenths: \(1 + 0 = 1\)
• Units: \(2 + 345 = 347\)

So total is \(347.174\).
