The correct answer for the expression 20 + 20 × 0 + 1 by applying the rule of PEMDAS is equal to 21.
To explain in detail, we follow the order of operations (also known as PEMDAS ) to solve this expression step by step:
Parentheses Exponents Multiplication and Division (from left to right)
Addition and Subtraction (from left to right)
Let's solve the expression step by step:
20 + 20 × 0 + 1
20 + (20 × 0) + 1 [There are no parentheses or brackets]
20 + (0) + 1 [Perform the multiplication first (20 × 0 = 0)]
20 + 0 + 1 [Perform the addition (20 + 0 = 20)]
20 + 1 [Perform the addition (20 + 1 = 21)]
Therefore , the value of the given expression is equal to 21.

The division of 3.1 by 10.261 will be 0.30.
In mathematics, the arithmetic operation has four main operators such as addition, subtraction, multiplication, and division.
The symbol of ÷ represents division.
Given the division of 3.1 by 10.261
Now,
3.1 / 10.261 = 0.302114803
If we round it up to the tenth decimal place then since a hundred places is 2 so it will not round up it will remain the same.
So 0.302114803 → 0.30
Hence "The division of 3.1 by 10.261 will be 0.30".

because 31 goes into 102o 3 times so 31x3=93
102-93=9
drop down the 6
now becomes 96
31 goes into 96 3 times
96-93=3
drop down 1
becomes 31
31 goes into 31 I time 31-31=0 so answer is 3.31
