Question 1. Solve:
(i) \( 406 + 313 = 719 \)
(ii) \( 723 + 189 = 912 \)
(iii) \( 653 + 333 = 986 \)
(iv) \( 700 - 599 = 101 \)
(v) \( 557 - 277 = 280 \)
Answer: These problems are basic arithmetic operations. We add or subtract the given numbers to find the correct result for each problem. Each calculation follows standard rules of addition and subtraction.
In simple words: For each problem, do the addition or subtraction shown to find the final number.

🎯 Exam Tip: Always double-check your addition and subtraction calculations to avoid simple errors, especially when dealing with multiple digits.

Question 6. \( 580 + 27 + 306 = \)
Answer: First, add the numbers step by step.
\( 580 + 27 = 607 \)
\( 607 + 306 = 913 \)
So, \( 580 + 27 + 306 = 913 \). Adding numbers one by one helps to keep track of the calculation correctly.
In simple words: To solve this, add the first two numbers, then add the third number to that result. The total sum is 913.

🎯 Exam Tip: When adding multiple numbers, it's often easiest to add them in pairs or stack them vertically to sum column by column.

Question 7. \( 473 - 296 = \)
Answer: To find the difference, we subtract 296 from 473.
\( 473 - 296 = 177 \)
The result of subtracting 296 from 473 is 177. Subtraction is used to find how much is left or the difference between two numbers.
In simple words: Subtract the smaller number 296 from the larger number 473 to find the difference, which is 177.

🎯 Exam Tip: For subtraction, always ensure you borrow correctly from the left column when a digit in the top number is smaller than the one below it.

Question 8. \( 364 + 67 - 199 = 431 - 199 = \)
Answer: First, perform the addition:
\( 364 + 67 = 431 \)
Then, perform the subtraction:
\( 431 - 199 = 232 \)
So, both parts of the expression result in 232. This shows how addition and subtraction are done in order.
In simple words: First, add 364 and 67 to get 431. Then, subtract 199 from 431. The answer is 232.

🎯 Exam Tip: Always perform operations in the correct order: first addition or subtraction from left to right as they appear in the problem.

Question 10. 185 boys and 162 girls are studying in Government Higher Secondary School, Udliyas. What is the total number of students studying in this school?
Answer: To find the total number of students, we need to add the number of boys and the number of girls. The school has 185 boys and 162 girls. When we add these two groups together, we get the total student count. The school has a total of 347 students.
In simple words: Add the number of boys (185) and girls (162) to find out how many students are in the school altogether. The total is 347.

🎯 Exam Tip: For questions asking for the 'total number,' always use addition. Clearly identify all quantities that need to be combined.

Question 11. In a garden 255 roses, 156 marigold, 178 Jasmine plants are there. What is the total number of flowering plants?
Answer: To find the total number of plants in the garden, we add the count of each type of flower. There are 255 rose plants, 156 marigold plants, and 178 jasmine plants. Adding these three numbers gives us the complete count of all flowering plants. The garden has a total of 559 flowering plants. Flowers add beauty and help attract pollinators like bees.
In simple words: Add the roses (255), marigolds (156), and jasmine plants (178) together. This sum tells us the grand total of flowers in the garden, which is 559.

🎯 Exam Tip: When adding three or more numbers, arrange them vertically and add column by column, carrying over tens when necessary, to ensure accuracy.

Question 12. Gita's father is at the mart to sell pots. This time her father built 523 pots, of which 484 were sold out. Then how many pots are left unsold?
Answer: To find out how many pots are left, we need to subtract the number of pots sold from the total number of pots built. Gita's father built 523 pots and sold 484. By taking away the sold pots from the total, we find the remaining pots. There are 39 pots left unsold.
In simple words: Subtract the pots sold (484) from the pots made (523). The number left is 39. This shows how many pots still need to be sold.

🎯 Exam Tip: Questions asking 'how many left' or 'difference' usually require subtraction. Make sure to subtract the smaller number from the larger one carefully.

Question 13. Do addition and subtraction with Indian numbers.
(i) \( ८५७ + ३२४ \)
(ii) \( ४६९ + २८५ \)
(iii) \( ६५७ + ४९३ \)
(iv) \( ८७९ - ४३५ \)
(v) \( ५९२ - ४८१ \)
(vi) \( ३५७ - १४६ \)
Answer:
(i) \( ८५७ + ३२४ = ११२१ \)
(ii) \( ४६९ + २८५ = ७५४ \)
(iii) \( ६५७ + ४९३ = ११५० \)
(iv) \( ८७९ - ४३५ = ४४४ \)
(v) \( ५९२ - ४८१ = १११ \)
(vi) \( ३५७ - १४६ = २११ \)
The calculations are performed just like with standard Arabic numerals, following the same rules for carrying and borrowing.
In simple words: These problems involve adding and subtracting numbers written in Indian numerals. The process is the same as with regular numbers: align them by place value and perform the operation.

🎯 Exam Tip: While the numerals are different, the rules of arithmetic (addition, subtraction, carrying, borrowing) remain the same. Practice recognizing Indian numerals to avoid confusion.

Question 14. Solve the following addition and subtraction problems.
(i) \( 3758 + 2637 \)
(ii) \( 8329 + 1671 \)
(iii) \( 9885 - 8905 \)
(iv) \( 6372 - 2863 \)
Answer:
(i) \( 3758 + 2637 = 6395 \)
(ii) \( 8329 + 1671 = 10000 \)
(iii) \( 9885 - 8905 = 980 \)
(iv) \( 6372 - 2863 = 3509 \)
These calculations combine both addition and subtraction, requiring careful attention to the operation symbol in each part.
In simple words: These are a mix of addition and subtraction problems. For addition, combine the numbers to get a total. For subtraction, find the difference between the two numbers.

🎯 Exam Tip: Pay close attention to the operation sign (+ or -) for each problem to avoid mixing them up. Always double-check your work to ensure accuracy.
