Question 2. The largest 1 digit number is ______________________________.
Answer: 9
In simple words: Nine is the biggest number that has only one digit. After nine comes ten, which has two digits.

Exam Tip: Successor = number + 1. So it is always 1 greater.

Question 23. A number that comes just before a given number is called its ____________________.
Answer: predecessor
In simple words: The number that comes right before another number is called its predecessor.

Exam Tip: "Pre-" means before, which helps you remember that predecessor is the number before.

Question 24. The predecessor of a number is ___________less than the number.

In simple words: To write these numbers, match each spoken value to its proper column (Thousands, Hundreds, Tens, Ones). If a column is not mentioned, fill it with a zero.

Exam Tip: Be careful with numbers like "nine thousand seven". There are no hundreds or tens, so we place zeros in those slots to get 9007.

In simple words: Read the digits in their place columns and write down how we say them out loud.

Exam Tip: When there is a zero in a place value slot, like the hundreds place in 9067, do not write "zero hundred" - just skip it and read the next part.

Question 37. Write the predecessor and successor of the given numbers:

Answer: See the completed table above.
In simple words: To find the predecessor, take away 1 from the number. To find the successor, add 1 to the number.

Question 40. Fill in the blanks using '<', '>' or '=':
8001 _____ 8001
1435 _____ 1435
Answer:
8001 = 8001

10. 3447, 3448, 3449, 3450, 3451, 3452
In simple words: Find the rule or difference between the numbers in each sequence, and then apply that same rule to write the next three numbers.

Exam Tip: Work out the pattern by subtracting the first number from the second number. This shows if you need to add or subtract, and by how much.

Question 42. Write the place value and face value of the encircled digits:

Answer: See the completed table above.
In simple words: Face value is just the digit itself. Place value is how much the digit is worth based on where it sits in the number.

2. 1425
3. 8042
4. 9607
In simple words: Add the expanded parts together to write the short, standard number.

Exam Tip: Check your zeroes carefully. In "8000 + 0 + 40 + 2", there are zero hundreds, so we must write a "0" in the hundreds place: 8042.

Question 44. Write the expanded form:
1. 5629 =

Question 45. Write the greatest and smallest 4 - digit number by using the given digits:
a) 9,5,6,4
b) 5,6,8,3

In simple words: To build the greatest number, arrange the digits from largest to smallest. To build the smallest number, arrange them from smallest to largest.

Exam Tip: If any digit is a zero, do not place it at the very beginning of the smallest number, as that would make it a three-digit number instead of a four-digit number.

Question 46. Write the ordinal numbers from 1 to 20:

Answer: See the completed table above.
In simple words: Ordinal numbers tell us the order or position of things, like who came first, second, or third.

In simple words: Compare the numbers to find the one with the highest value.

Exam Tip: Look at the thousands place first, then the hundreds, tens, and ones places in order to spot the biggest number.

Question 48. Circle the smallest number:
a) 1357, 1753, 1573, 1735, 1537

Answer: addends
In simple words: The numbers that we add together are called addends.

Exam Tip: In the equation 5 + 4 = 9, the numbers 5 and 4 are the addends.

Question 52. The answer of addition is called __________________________.
Answer: sum
In simple words: The total value we get when we add numbers together is called the sum.

Answer: sum
In simple words: No matter which number you add first, the final answer stays exactly the same.

Exam Tip: This rule is called the order property of addition (for example, 4 + 3 is equal to 3 + 4).

Question 54. The sum of zero and any number is the ______________________.
Answer: number itself
In simple words: When you add zero to any number, the value does not change.

Exam Tip: This is the identity property of addition. For example, 7 + 0 = 7.

Question 55. When we add _____________ to a number the answer is the number after.
Answer: 1
In simple words: Adding 1 to any number gives you its successor, or the very next number.

Question 59. 15 + 10 = 25, the addends are _________, __________ and the sum is _____________.
Answer: 15, 10, 25
In simple words: In this math problem, 15 and 10 are the parts we add together, and 25 is our final answer.

Exam Tip: Identify the parts of an addition problem carefully: addend + addend = sum.

Question 60. The ______________is always greater than the numbers being added, except when one of the numbers being added is zero.
Answer: sum
In simple words: Adding positive numbers always gives a total that is larger than the starting numbers, unless you add zero.

Question 61. 19 + 20 + 7 = 20 + _____ + 19.
Answer: 7
In simple words: Even when we swap the order of the numbers we are adding, we must use the exact same three numbers on both sides.

Exam Tip: Match the list of numbers on both sides of the equals sign to spot the missing value immediately.

Question 62. Add the following:

Answer: See the calculations above.
In simple words: Add the columns starting from the ones place on the right, and carry over any extra tens to the next column on the left.

Answer:
Number of chocolate milk bottles sold = 6200
Number of strawberry milk bottles sold = 3780
Total bottles sold = 6200 + 3780 = 9980
The shop sold 9980 bottles in all.

Answer:
Number of apple trees = 4358
Number of mango trees = 3850
Number of coconut trees = 2900
Total number of trees = 4358 + 3850 + 2900 = 11108
There are 11,108 trees in all on the farm.
