Problem: Solve the basic arithmetic operations as given in the image.
The tasks are divided into three sections:
1.
Addition
2.
Subtraction
3.
Multiplication
Let's solve each section step by step.
---
1. Addition
We need to add the pairs of numbers:
#### (a) \( 91 + 13 \)
\[
91 + 13 = 104
\]
#### (b) \( 10 + 82 \)
\[
10 + 82 = 92
\]
#### (c) \( 64 + 7 \)
\[
64 + 7 = 71
\]
#### (d) \( 175 + 889 \)
\[
175 + 889 = 1064
\]
#### (e) \( 405 + 671 \)
\[
405 + 671 = 1076
\]
#### (f) \( 146 + 680 \)
\[
146 + 680 = 826
\]
Results for Addition:
\[
104, 92, 71, 1064, 1076, 826
\]
---
2. Subtraction
We need to subtract the second number from the first number in each pair:
#### (a) \( 20 - 13 \)
\[
20 - 13 = 7
\]
#### (b) \( 33 - 15 \)
\[
33 - 15 = 18
\]
#### (c) \( 43 - 26 \)
\[
43 - 26 = 17
\]
#### (d) \( 932 - 176 \)
\[
932 - 176 = 756
\]
#### (e) \( 825 - 763 \)
\[
825 - 763 = 62
\]
#### (f) \( 4260 - 2128 \)
\[
4260 - 2128 = 2132
\]
Results for Subtraction:
\[
7, 18, 17, 756, 62, 2132
\]
---
3. Multiplication
We need to multiply the pairs of numbers. This section is divided into two parts.
#### Part (a):
##### (i) \( 99 \times 5 \)
\[
99 \times 5 = 495
\]
##### (ii) \( 73 \times 8 \)
\[
73 \times 8 = 584
\]
##### (iii) \( 435 \times 9 \)
\[
435 \times 9 = 3915
\]
##### (iv) \( 199 \times 6 \)
\[
199 \times 6 = 1194
\]
##### (v) \( 7988 \times 3 \)
\[
7988 \times 3 = 23964
\]
##### (vi) \( 1822 \times 7 \)
\[
1822 \times 7 = 12754
\]
Results for Part (a):
\[
495, 584, 3915, 1194, 23964, 12754
\]
#### Part (b):
##### (i) \( 56 \times 15 \)
\[
56 \times 15 = 840
\]
##### (ii) \( 39 \times 24 \)
\[
39 \times 24 = 936
\]
##### (iii) \( 21 \times 74 \)
\[
21 \times 74 = 1554
\]
##### (iv) \( 96 \times 94 \)
\[
96 \times 94 = 9024
\]
##### (v) \( 92 \times 99 \)
\[
92 \times 99 = 9108
\]
Results for Part (b):
\[
840, 936, 1554, 9024, 9108
\]
---
Final Answers
Combining all the results:
-
Addition: \( 104, 92, 71, 1064, 1076, 826 \)
-
Subtraction: \( 7, 18, 17, 756, 62, 2132 \)
-
Multiplication (Part a): \( 495, 584, 3915, 1194, 23964, 12754 \)
-
Multiplication (Part b): \( 840, 936, 1554, 9024, 9108 \)
\[
\boxed{
\begin{aligned}
&\text{Addition: } 104, 92, 71, 1064, 1076, 826 \\
&\text{Subtraction: } 7, 18, 17, 756, 62, 2132 \\
&\text{Multiplication (Part a): } 495, 584, 3915, 1194, 23964, 12754 \\
&\text{Multiplication (Part b): } 840, 936, 1554, 9024, 9108
\end{aligned}
}
