FIRST GRADE
WHAT IS 7+7?
Correct Answer
A. 14
Explanation
The correct answer is 14 because when you add 7 and 7 together, you get a sum of 14.
3.
What shape has four sides of equal length and four corners?
Correct Answer
Square, SQUARE, square , Rhombus , rhombus , RHOMBUS
Explanation
A square is a special type of rhombus where all four angles are right angles (90 degrees), making it both a rhombus and a rectangle. Therefore, a square has four equal sides and four right angles.
A rhombus has four sides of equal length, but its angles are not necessarily 90 degrees. The opposite angles in a rhombus are equal, and the adjacent angles are supplementary (add up to 180 degrees).

WHAT IS 4X4+5=?
Correct Answer
B. 21
Explanation
To solve 4×4+5, we follow the order of operations:
Multiplication first:
4×4=16
Addition next:
16+5=21
So, 4×4+5=21
5.
The number 6 is prime no. or composite no. or neither?
Correct Answer
B. COMPOSITE
Explanation
The number 6 is composite because it can be divided evenly by numbers other than 1 and itself. In the case of 6, it can be divided by 2 and 3 without leaving a remainder. This means that 6 is not a prime number, which is defined as a number that can only be divided by 1 and itself. Therefore, the correct answer is composite.

DIRIVATIVES/12TH
WHAT IS THE FIRST DIRIVATIVE OF 6X+4?
Correct Answer
A. 6
Explanation
The first derivative of 6x+4 is 6. This is because when we take the derivative of a constant term (in this case, 4), it becomes 0. The derivative of 6x is 6, as the power of x is reduced by 1 and the coefficient (6) remains the same. Therefore, the first derivative of 6x+4 is 6.
7.
WHAT IS THE FIRST DIRIVATIVE OF 4?
Correct Answer
A. 0
Explanation
The first derivative of a constant value is always 0. In this case, the constant value is 4, so its first derivative will be 0. The first derivative represents the rate of change of a function at a given point, and since the function is a constant, it does not change and therefore has no rate of change.
8.
DOES A LINE HAVE SYMMETRY
Correct Answer
A. YES
Explanation
A line has symmetry because it can be divided into two equal parts that are mirror images of each other.
9.
DOES 1+1=2
Correct Answer
A. YES
Explanation
The answer is "YES" because in basic arithmetic, when you add 1 and 1 together, the result is 2.
10.
IS 5 PRIME
Correct Answer
A. True
Explanation
The number 5 is considered prime because it is only divisible by 1 and itself. It does not have any other factors. Prime numbers are unique in that they cannot be formed by multiplying two smaller numbers together.
11.
What is the sum of 7 and 5?
Correct Answer
B. 12
Explanation
B is correct because adding 7 and 5 equals 12. To find the sum, you add the two numbers: 7 + 5 = 12. This basic math operation combines the values of the numbers to get a total. Knowing how to add is essential in math and helps with more complex calculations.
12.
What is the value of 8 + (3 * 4)?
Correct Answer
A. 20
Explanation
First, follow the order of operations (PEMDAS/BODMAS):
Perform the multiplication inside the parentheses: 3 * 4 = 12
Then, add the result to 8: 8 + 12 = 20
So, the correct answer is 20.
