Check Rashi’s subtraction using addition. 4 6 8 - 1 3 9 2 2 1

In the given question we need to check whether Rashi's subtraction is right. 4 6 8 - 1 3 9 2 2 1 Minuend - Subtrahend = Difference Here, minuend = 468 Subtrahend = 139 Difference = 221 Addition is inverse of subtraction. Therefore, if the sum of difference and subtrahend results the given minuend, then the subtraction is right otherwise wrong. 2 2 1 + 1 3 9 3 6 0 Here, the sum = 221 + 139 = 360 The sum is not equal to minuend, therefore, the given subtraction is wrong.

Check Rashi's subtraction using addition. 3 5 6 - 2 4 7 1 1 9

In the given question we need to check whether Rashi's subtraction is right. Given, 3 5 6 - 2 4 7 1 1 9 Here, minuend = 356 Subtrahend = 247 Difference = 119 Addition is inverse of subtraction. Therefore, if the sum of difference and subtrahend results the given minuend, then the subtraction is right otherwise wrong. 1 1 9 + 2 4 7 3 6 6 Here, the sum = 119 + 247 = 366 The sum is not equal to minuend, therefore, the given subtraction is wrong.

Find the missing numbers: 7 8 - 3 ? ? 5

Given, 7 8 - 3 ? ? 5 Here, minuend = 78 While subtracting two digit numbers always subtract ones first and then tens. Ones place: 8 - ? = 5 Subtract 5 from 8 to find the missing number. 8 - 5 = 3 Tens place: 7 - 3 = 4 Thus, 7 8 - 3 3 4 5 Therefore, the required answer is shown above.

Find the missing numbers: 2 1 ? - 1 ? 7 ? 3 2

Given, 2 1 ? - 1 ? 7 ? 3 2 Minuend - Subtrahend = Difference. Addition is the inverse of subtraction. Subtrahend + Difference = Minuend ⇒ 7 + 2 = 9 Hence, missing number in units place column is 9 . Since, minuend is less than difference. So, borrow one hundred from hundreds place. 1 hundred + 1 ten = 10 tens + 1 ten = 11 tens ⇒ 11 - 3 = 8 Hence, missing number in ten's place column is 8 Now, subtract hundreds place, 1 - 1 = 0 Hence, missing number in hundreds place column is 0 Therefore, the required answer is 2 1 9 - 1 8 7 0 3 2 .

Find the missing numbers: ? 6 - 3 ? 6 0

Given, ? 6 - 3 ? 6 0 Minuend - Subtrahend = Difference Minuend - Difference = Subtrahend ⇒ 6 - 0 = 6 Hence, missing number in units place column is 6 Now, to find missing number in tens place column, Subtrahend + Difference = Minuend ⇒ 3 + 6 = 9 Hence, missing number in tens place column is 9 9 6 - 3 6 6 0 Hence, the missing numbers are 9 in tens column and 6 in units column.

Find the missing numbers: ? 4 4 - 2 3 8 2 ? ?

Given, ? 4 4 - 2 3 8 2 ? ? Minuend - Subtrahend = Difference Since, minuend is less than subtrahend, borrow one ten from tens place. 1 ten + 4 ones = 14 ones ⇒ 14 - 8 = 6 Hence, missing number in units place is 6 . 3 - 3 = 0 Hence, missing number in tens place is 0 Subtrahend + Difference = Minuend ⇒ 2 + 2 = 4 Hence, missing number in hundreds place is 4 4 4 4 - 2 3 8 2 0 6

Let's deliver letters. Postman uncle is ill today lets deliver letters for him. Write the correct room numbers on the letters, then find the rooms in the above building and circle them.

We need to perform addition or subtraction operation given in the card to find the room number. 445 + 10 = 455 456 - 20 = 436 430 + 20 + 13 = 430 + 20 + 10 + 3 = 463 426 + 38 = 420 + 6 + 30 + 8 = 464 467 + 11 = 460 + 7 + 10 + 1 = 478 480 - 9 = 471 429 + 10 + 20 = 459 450 - 19 = 431 498 - 23 = 475 466 - 33 = 433 452 + 18 = 450 + 2 + 10 + 8 = 470 410 + 13 + 11 = 410 + 10 + 3 + 10 + 1 = 434 430 + 15 = 430 + 10 + 5 = 445 467 + 22 = 460 + 7 + 20 + 2 = 489 461 + 25 = 460 + 20 + 5 = 486 Hence, the cards with room number and circled rooms are shown above.
