To understand subtraction, children must understand algorithms, symbols, and quantity.

Subtraction is a mathematical operation that involves taking away one quantity from another. In order to comprehend subtraction, children need to understand how to perform the subtraction algorithm, which involves the steps of aligning the numbers, borrowing if necessary, and subtracting each place value from right to left.

They also need to understand the symbols used in subtraction, which commonly include the minus sign (-) and the subtraction symbol (—). These symbols indicate the operation of taking away or subtracting one quantity from another.

Moreover, children need to have a grasp of quantity in order to subtract. This entails recognizing and understanding the concept of "how many" or the numerical value of the numbers involved in the subtraction. For example, understanding that subtracting 3 from 8 means starting with 8 and removing 3 items.

Patterning and sequencing (option A) are not directly related to understanding subtraction, although they may be useful in some problem-solving contexts. Fractions (option C) are not typically introduced in the early stages of learning subtraction. Estimation (option D) is a valuable skill, but it is not a prerequisite for understanding subtraction. Therefore, option B, algorithms, symbols, and quantity, is the most appropriate choice.
