In mathematics, a neutral element is an element that does not alter the rest of the numbers when we perform an operation with it.
With addition, is considered a neutral element because it does not modify the number to which it is added.
In multiplication, is considered a neutral element because it does not affect the result.
The neutral element in subtraction is , while in division it is .
\( (3\times5-15\times1)+3-2= \)
Note that in a multiplication operation, is not considered a neutral number because it affects the the number it is multiplied with by changing its sign.
\( (5\times4-10\times2)\times(3-5)= \)
\( (5+4-3)^2:(5\times2-10\times1)= \)
\( 8\times(5\times1)= \)
A neutral element is a number that does not alter the other numbers when an operation is applied to it.
The only neutral element for addition is and zero is not part of the set of natural numbers. Therefore, there is no neutral of addition in this set.
\( 7\times1+\frac{1}{2}= \)
\( \frac{6}{3}\times1= \)
\( 12+3\times0= \)
If there is a non-zero number a and we must find the value of when , then by solving the equation we find that the neutral of the product is 1.
The neutral element for division is .
\( 2+0:3= \)
\( 19+1-0= \)
\( 9-0+0.5= \)
The absorbing element of multiplication is 0 because any number multiplied by is .
The additive neutral of real numbers does not modify the value of any number that it is added to.
Example: is the additive neutral of real numbers since .
\( \frac{1}{2}+0+\frac{1}{2}= \) ?
\( 0+0.2+0.6= \)
\( 12+1+0= \)

Well, yes! This is because there will be some subjects that come to you easily, while others may take you longer to grasp.
\( 0:7+1= \)
\( \frac{25+25}{10}= \)
\( (3\times5-15\times1)+3-2= \)
\( (5\times4-10\times2)\times(3-5)= \)
\( (5+4-3)^2:(5\times2-10\times1)= \)
\( 8\times(5\times1)= \)
According to the order of operations, we first solve the expression in parentheses:
Now we multiply:
40
According to the order of operations rules, we first insert the multiplication exercise into parentheses:
Let's solve the exercise inside the parentheses:
And now we get the exercise:
According to the order of operations rules, we will solve the exercise from left to right, since there are only multiplication and division operations:
This simple rule is the order of operations which states that exponentiation precedes multiplication and division, which precede addition and subtraction, and that operations enclosed in parentheses precede all others,
Following the simple rule, multiplication comes before division and subtraction, therefore we calculate the values of the multiplications and then proceed with the operations of division and subtraction
Therefore, the correct answer is answer B.
This simple rule is the order of operations which states that multiplication precedes addition and subtraction, and division precedes all of them,
In the given example, a multiplication occurs between two sets of parentheses, thus we simplify the expressions within each pair of parentheses separately,
We start with simplifying the expression within the parentheses on the left, this is done in accordance with the order of operations mentioned above, meaning that multiplication comes before subtraction, we perform the multiplications in this expression first and then proceed with the subtraction operations within it, in reverse we simplify the expression within the parentheses on the right and perform the subtraction operation within them:
What remains for us is to perform the last multiplication that was deferred, it is the multiplication that occurred between the expressions within the parentheses in the original expression, we perform it while remembering that multiplying any number by 0 will result in 0:
Therefore, the correct answer is answer d.
