Calculation Details
2 and 5 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 2 and 5.
Ones+25
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 2 and 5 in the Ones place are added together, and the result is 7.
Ones+257A 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: 2 + 5.1.1The point representing 2 on the number line is moved 5 units to the right along the number line, and the result is 7.Therefore, the Ones place calculation yields 7, as 2 + 5 = 7.01(1)23456789101112(1)The point representing 2 on the number line is moved 5 units to the right along the number line, and the result is 7.
3
Calculate 2 + 5. The result is 7.

Summarize
Therefore, 2 + 5 equals 7.
