What is the same difference strategy?
The strategy of ‘same difference’ is consistent with the principle already established in our primary schools that we encourage children to adopt sensible mental approaches, where the numbers involved influence the choice of strategy.
What is the same difference Theorem?
Generalise the idea that adding or subtracting the same number from both numbers in any pair conserves the difference between them. Progress to problems in which finding differences between two-digit numbers is made easier by adding or subtracting the same amount from both numbers.
What is an equivalent difference?
Equal and equivalent are terms that are used frequently in mathematics. The main difference between equal and equivalent is that the term equal refers to things that are similar in all aspects, whereas the term equivalent refers to things that are similar in a particular aspect.
What are equal factors?
A root of a number is one of two or more equal numbers that, when multiplied together, will produce the number. Such a number is called an equal factor. Thus, two equal factors that will produce 9 when multiplied together are 3 and 3. Therefore, the square root of 9 equals 3. This may be written (sqrt) 9 = 3.
What does Same difference mean in math?
In a mathematical sense, it has some value (7-2=5 and 10-5=5; “same difference”), but otherwise if all this means is “the two things are the same” then it is confusing and wordy. One could say “same thing” and save 50% of the syllables and avoid potential confusion.
How will you explain to a student the difference between equality and equivalence of sets?
Equal sets have the exact same elements in them, even though they could be out of order. Equivalent sets have different elements but have the same amount of elements.
What’s the difference between equivalence and equality?
The main difference between equal and equivalent is that the term equal refers to things that are similar in all aspects, whereas the term equivalent refers to things that are similar in a particular aspect. Note that in the set theory, the words “equal” and “equivalent” have specific meanings, as we will see below.
What is a factor tree?
Factor trees are a way of expressing the factors of a number, specifically the prime factorization of a number. Each branch in the tree is split into factors. Once the factor at the end of the branch is a prime number, the only two factors are itself and one so the branch stops and we circle the number.
What term refers to the product of equal factors?
In mathematics, a product is the result of multiplication, or an expression that identifies factors to be multiplied. For example, 30 is the product of 6 and 5 (the result of multiplication), and is the product of and.
What does Same difference mean?
Definition of same difference —used to say that two things are not really different in any important way “They lost 100 games last year.” “Actually, they only lost 96 games.” “Same difference. The point is, they were awful.”
Why do we say same difference?
Same difference is an informal phrase referring to two or more alternatives that while different, render the same outcome or so close to the same outcome that the difference is negligible. Same difference is used when two different things are different, but equivalent.
What is the difference between equal and equivalent sets examples?
