Maths Class 4 And 5

An even number is defined as a number that is divisible by 2 without leaving a remainder. However, 5 is not divisible by 2 and leaves a remainder of 1. Therefore, 5 is an odd number.

The symbol "L" in Roman numerals represents the number 50. In Hindu-Arabic numerals, the number 50 is also represented by the digit 5.

The given statement "division is repeated addition" is false. Division is the inverse operation of multiplication, not addition. While addition can be used to solve some division problems, it is not an accurate representation of division as a whole. Division involves splitting a quantity into equal parts or finding how many times one number can be divided by another. It is a distinct mathematical operation that is different from repeated addition.

The given expression involves addition, subtraction, and multiplication operations. According to the order of operations (PEMDAS/BODMAS), multiplication is performed before addition and subtraction. Therefore, the expression is simplified as follows: 1 + 2 - (3 * 4) = 1 + 2 - 12 = 3 - 12 = -9. Hence, the correct answer is not 0.

The correct answer is 7* 7 = 49 because when you multiply 7 by itself, you get the product of 49.

The given equation states that 1000 is equal to some number of tens multiplied by 100. To find the number of tens, we can divide 1000 by 100. The result of this division is 10, which means that there are 10 tens in 1000. Therefore, the correct answer is 100.

A palindrome is a number that reads the same forwards and backwards. In this case, the number 2112 reads the same whether it is read from left to right or right to left, making it a palindrome.

The answer states that 2 and 4 are the basic even numbers, which is correct because both 2 and 4 are divisible by 2 and do not have a remainder. Additionally, the answer states that 3 and 5 are the basic odd numbers, which is also correct because both 3 and 5 are not divisible by 2 and have a remainder of 1 when divided by 2.

A cuboid has 12 sides because it is a three-dimensional shape with six rectangular faces. Each face has four sides, so 6 multiplied by 4 equals 12.
