Solution Process
For the convenience of calculation, the number with more integer digits is usually written on the top.
1
Commutative property of addition: When two addends are added, the sum remains the same if the positions of the addends are swapped. That is, a + b = b + a.

For the convenience of calculation, the number with more integer digits is usually written on the top.
1
Swap the positions of the addends.
1
The number of integer digits in 266 is greater than the number of integer digits in 10.
2
For the convenience of calculation, the number with more integer digits is usually written on the top.

Calculation Details
266 and 10 are all positive numbers.
Numbers with the same symbol are added, the symbol of the result remains the same, and the absolute value is added.
1
In vertical addition or subtraction, ensure that digits with the same place value are aligned.
1
The same digits must be aligned, usually starting from the ones digit; when calculating addition and subtraction of decimals, the decimal points must be aligned first.
2
Align the Ones digits 6 and 0.

3
Align the Tens digits 6 and 1.

4
Align the Hundreds digits 2.

2
In addition and subtraction, start calculations from the rightmost digit.
1
In math addition and subtraction, start at the last digit and work your way to the left, digit by digit, until the calculation is complete.
2
The numbers 6 and 0 in the Ones place are added together, and the result is 6.
HundredsTensOnes+261606A more intuitive calculation method is to use a number line, where the point representing a number on the number line increases from left to right and decreases from right to left. Therefore, addition can be performed by moving to the right along the number line.1.Ones place: 6 + 0.1.1The point representing 6 on the number line is moved 0 units to the right along the number line, and the result is 6.Finally, the Ones place calculation yields 6, as 6 + 0 = 6.01234567891011(1)The point representing 6 on the number line is moved 0 units to the right along the number line, and the result is 6.
3
The numbers 6 and 1 in the Tens place are added together, and the result is 7.
HundredsTensOnes+2616076A more intuitive calculation method is to use a number line, where the point representing a number on the number line increases from left to right and decreases from right to left. Therefore, addition can be performed by moving to the right along the number line.1.Tens place: 6 + 1.1.1The point representing 6 on the number line is moved 1 units to the right along the number line, and the result is 7.Finally, the Tens place calculation yields 7, as 6 + 1 = 7.012345(1)6789101112(1)The point representing 6 on the number line is moved 1 units to the right along the number line, and the result is 7.
4
The 2 in the Hundreds place remains unchanged.

3
Calculate 266 + 10. The result is 276.

Summarize
Finally, 10 + 266 equals 276.
