Which number multiplication and addition is same?
1,2 and 3 because this three are positive numbers and when added and multipled both gives the same answer 6. 1,2 and 3 are the positive integers and the result of their addition and their multiplication is same . 1, 2 and 3 are the result. therefore the answer is 1,2,3.
Is multiplication done before addition?
Order of operations tells you to perform multiplication and division first, working from left to right, before doing addition and subtraction.
Which is correct MDAS or DMAS?
It’s not MDAS. It’s actually DMAS, which means division, multiplication, addition and subtraction. In mathematics, this rule is followed which means in an equation or a problem, the order of simplification will be in the above format.
Does addition come before multiplication?
The order of operations is the order you use to work out math expressions: parentheses, exponents, multiplication, division, addition, subtraction. However, multiplication and division MUST come before addition and subtraction. The acronym PEMDAS is often used to remember this order.
What is the answer in addition called?
the sum
The answer of addition is called the sum, the answer of subtraction is called the difference, when minuend = subtrahend, difference is Zero.
What are three numbers whose addition and multiplication is the same?
Thank you for the question. 1,2 and 3 are the numbers whose addition and multiplication is the same. Multiply three numbers : 1*2*3 =6 . Addition three numbers : 1+2+3=6 . What about 1, 1 + Sqrt (2), 1 + Sqrt (2)?
How to check multiplication answers using digit sums?
We will look at how we can use digit sums to check our multiplication answers. The digit sum of a number is found by adding all the digits in the number. If the sum is more than one digit, we add all the digits again until we get a single digit answer. For example: To find the digit sum of 35, we add 3 + 5. So the digit sum is 8.
What happens if the digit sums are not equal?
So, if the digit sums you get are equal then your multiplication answer is most probably correct*. If the digit sums are not equal, then your answer is definitely incorrect! [ *If your answer has the same set of digits as the correct answer like 3,939, it will give the same digit sum even if it is not correct. ]
Which is the digit sum of two numbers?
When we multiply two numbers, the digit sum of the product of their digit sums will be equal to the digit sum of the product of the original numbers. That’s quite a mouthful! Let’s take an example so we get how simple it really is: The digit sum of 363 is 3. The digit sum of 11 is 2.
