Is reduction a subtraction?
Reduction involves reducing the value of a quantity and is often referred to as 'take away'. It is important that the language of 'take away' is only used with this concept for subtraction and not for other concepts for subtraction.
What does reduced mean in math?

The product of two numbers is the result you get when you multiply them together. So 12 is the product of 3 and 4, 20 is the product of 4 and 5 and so on.
What is Reductional and equational division?
The key difference between equational division and reduction division is that equational division refers to meiosis II, during which the chromosomal number remains equal as haploid. In contrast, reduction division refers to meiosis I, during which the chromosome number reduces to half from the diploid state.
Which is equational division?
Explanation: Mitosis is called equational division because each of the two daughter cells formed, get the same number of chromosomes as the parent.
What does "subtraction" mean?

Why draw boxes instead of circles?
In drawing models, we draw boxes instead of circles to represent numbers.The main idea is still the same - numbers can combine to to form larger numbers or be broken into smaller numbers. This method can be more accurate because we can draw bigger boxes to represent bigger numbers.
What is the equation for 3 + ___?
3 + ___ = 8 (this looks like an addition question, but it is solved using subtraction: 8 - 3)
Can a number be broken into smaller numbers?
A number can be broken into smaller numbers. This number bond shows that two smaller numbers (3, 4) can combine to make a larger number (7). This number bond shows that a larger number (7) can be 'split' into two smaller numbers (5, 2). Use physical objects like buttons, toys and so on to demonstrate the idea of number bonds.
Is subtraction related to addition?
Subtraction is closely related to addition. Sometimes it is not so easy to tell which operation to use. See these examples:
What is the second model of subtraction?
The second model of subtraction is partitioning . As pupils have become comfortable with subtraction being regarded as ‘taking away’, partitioning questions can prove challenging initially; pupils come to conclude that subtraction is only used when a quantity is being taken away.
Which model of subtraction is often mistaken for being the only model of subtraction?
The first subtraction structure is the reduction model, and this is the model that is often mistaken for being the only model of subtraction, leading to such confusions as pupils (and many adults) referring to the subtraction sign as ‘take away’; this is only accurate when the subtraction follows the reduction structure.
What does the mathematical symbol mean in math?
As with all topics within Maths, the mathematical language we use (and which we insist on pupils using) in the classroom when teaching subtraction is of critical importance if pupils are to avoid all too common misconceptions; specifically, the mathematical symbol – means ‘subtract’, not ‘take-away’.
When a subtraction question requires partitioning, what is the first number?
When a subtraction question requires partitioning, the first number (minuend) is being split into two parts (the subtrahend and the difference). Crucially, nothing is being lost when partitioning occurs, yet subtraction is still necessary to calculate the answer.
Is subtraction a routine operation?
As one of the four number operations, subtraction is a concept that is familiar – and indeed possibly routine – to every primary school teacher. Yet, it is perhaps surprisingly complicated. Subtraction has three separate structures.
Is reduction taught first?
Reduction is generally taught first, and as pupils progress through primary school, they encounter the partitioning and difference structures. Yet, it is crucial that pupils who are nearing the end of their primary career continue to read, understand and answer reduction questions.
