Fill in the boxes with correct digits. TL L TTh Th H T O 9 8 4 □ 6 2 + 3 6 □ 4 8 9 □ 4 6 3 □ 4 □ 9

We need to write missing numbers in the boxes TL L TTh Th H T O 9 8 4 □ 6 2 + 3 6 □ 4 8 9 □ 4 6 3 □ 4 □ 9 Adding the digits in ones place: 2 + □ = 9 To get 9 , we need to add 7 to 2 . So, 2 + 7 = 9 Adding the digits in tens place: 6 + 9 = 15 Adding the digits in hundreds place with carry: 1 + □ + 8 = 14 ∵ 4 < 8 ⇒ 9 + □ = 14 To get 14 , we need to add 5 to 9 . So, 1 + 5 + 8 = 14 Adding thousands place: 4 + 4 + 1 = 9 Adding ten thousand place: 8 + □ = 13 ∵ 8 > 3 To get 13 , we need to add 5 to 8 . So, 8 + 5 = 13 As there are no missing digits in lakhs and ten lakhs column, we need not do calculations for those columns. Hence, the completed addition is as shown below.

Fill in the boxes with correct digits. TL L TTh Th H T O 4 5 6 □ 8 □ + 1 □ 3 4 5 □ 7 1 6 □ □ 3 5 6

We need to write missing digits in the boxes TL L TTh Th H T O 4 5 6 □ 8 □ + 1 □ 3 4 5 □ 7 1 6 □ □ 3 5 6 Adding the digits in ones place: □ + 7 = 16 ∵ 6 < 7 To get 16 , we need to add 9 to 7 . So, 9 + 7 = 16 Adding the digits in tens place with carry: 1 + 8 + □ = 15 ∵ 5 < 8 To get 15 , we need to add 6 to 9 . So, 1 + 8 + 6 = 15 Adding the digits in hundreds place with carry: 1 + □ + 5 = 13 ∵ 3 < 5 To get 13 , we need to add 7 to 6 . So, 1 + 7 + 5 = 13 Adding digits in thousands place with carry: 1 + 6 + 4 = 11 Adding the digits in ten thousand place with carry: 1 + 5 + 3 = 9 Adding the digits in lakhs place: 4 + □ = 6 To get 6 , we need to add 2 to 4 . So, 4 + 2 = 6 Hence, the completed addition is as shown below. TL L TTh Th H T O Carry 1 1 1 1 4 5 6 7 8 9 + 1 2 3 4 5 6 7 1 6 9 1 3 5 6

Fill in the boxes with correct digits. L TTh Th H T O □ 7 8 5 4 6 + 3 □ □ 5 □ 6 5 9 1 □ 9 □

We need to write missing digits in the boxes L TTh Th H T O □ 7 8 5 4 6 + 3 □ □ 5 □ 6 5 9 1 □ 9 □ Adding the digits in ones place: 6 + 6 = 12 Adding the digits in tens place with carry: 1 + 4 + □ = 9 To get 9 , we need to add 4 to 5 . So, 1 + 4 + 4 = 9 Adding the digits in hundreds place: 5 + 5 = 10 Adding digits in thousands place: 1 + 8 + □ = 11 ∵ 1 < 8 To get 11 , we need to add 2 to 9 . So, 1 + 8 + 2 = 11 Adding the digits in ten thousand place with carry: 1 + 7 + □ = 9 To get 9 , we need to add 1 to 8 . So, 1 + 7 + 1 = 9 Adding the digits in lakhs place: □ + 3 = 5 To get 5 , we need to add 2 to 3 . So, 2 + 3 = 5 Hence, the completed addition is as shown below.

Fill in the boxes with correct digits : L TTh Th H T O 8 9 6 5 2 - 6 6 4 8 2 5 3 8 9

The given subtraction of numbers with missing digits is: L TTh Th H T O 8 9 6 5 2 - 6 6 4 8 2 5 3 8 9 Let us start subtracting from ones place. Subtract ones: 12 - 8 = 4 . Subtract tens: - 4 = 9 ⇒ = 9 + 4 ⇒ = 13 Since 1 is borrowed to ones place, so in tens place we have 3 + 1 = 4 . Subtract hundreds: 14 - 6 = 8 . Subtract thousands: 5 - = 2 ⇒ = 5 - 2 ⇒ = 3 Subtract ten thousands: 9 - = 5 ⇒ = 9 - 5 ⇒ = 4 Now, filling the missing digits we get, L TTh Th H T O 5 14 3 12 8 9 6 5 4 2 - 6 4 2 6 4 8 2 5 3 8 9 4 Hence, the difference is 253894 .

The given subtraction of numbers with missing digits is: L TTh Th H T O 3 5 7 5 - 2 8 6 5 3 2 0 0 Let us start subtracting from ones place. Subtract ones: 5 - 5 = 0 . Subtract tens: 7 - 6 = ⇒ = 1 Subtract hundreds: - 8 = 0 ⇒ = 0 + 8 ⇒ = 8 Subtract thousands: 5 - = 0 ⇒ = 5 - 0 ⇒ = 5 Subtract ten thousands: - 2 = 2 ⇒ = 2 + 2 ⇒ = 4 Now, filling the missing digits we get, L TTh Th H T O 3 4 5 8 7 5 - 2 5 8 6 5 3 2 0 0 1 0 Hence, the difference is 320010 .

Fill in the boxes with correct digits : L TTh Th H T O 9 6 4 8 - 3 5 6 8 5 6 9 9

The given subtraction of numbers with missing digits is: L TTh Th H T O 9 6 4 8 - 3 5 6 8 5 6 9 9 Let us start subtracting from ones place. Subtract ones: 18 - = 9 ⇒ = 18 - 9 ⇒ = 9 Subtract tens: 13 - = 9 ⇒ = 13 - 9 ⇒ = 4 Subtract hundreds: - 8 = 6 ⇒ = 6 + 8 ⇒ = 14 Since we have borrowed 1 to tens place, so we have 14 + 1 = 15 in hundreds place. Subtract thousands: 15 - 6 = ⇒ = 9 Subtract ten thousands: 8 - 5 = ⇒ = 3 Subtract lakhs: - 3 = 5 ⇒ = 5 + 3 ⇒ = 8 Now, filling the missing digits we get, L TTh Th H T O 8 15 14 13 18 8 9 6 5 4 8 - 3 5 6 8 4 9 5 3 9 6 9 9 Hence, the difference is 539699 .
