Studdy Solution

STEP 1

Assumptions
1. We are performing an addition operation.
2. The numbers to be added are 2.6 and 2.1.

STEP 2

To perform the addition, align the numbers vertically, ensuring that the decimal points are lined up.
+2.6+.2.1 \begin{align*} &\phantom{+}2.6\\ +&\phantom{.}2.1\\ \end{align*}

STEP 3

Add the numbers starting from the rightmost digit, which is after the decimal point.
+2.6+.2.1+4.7 \begin{align*} &\phantom{+}2.6\\ +&\phantom{.}2.1\\ \hline &\phantom{+}4.7\\ \end{align*}

STEP 4

The sum of the numbers after the decimal point is 6 + 1 = 7, which is placed directly after the decimal point in the sum.

STEP 5

The sum of the numbers before the decimal point is 2 + 2 = 4, which is placed before the decimal point in the sum.

STEP 6

Combine the sums before and after the decimal point to get the final answer.
2.6+2.1=4.7 2.6 + 2.1 = 4.7

STEP 7

To check the work using a calculator, simply enter 2.6, press the addition (+) button, then enter 2.1, and finally press the equals (=) button. The calculator should display 4.7.
The solution to the operation is 4.7.
