If only one number be 1 then the product cannot be 1. Examples: 5 x 1 = 5, 4 x 1 = 4, 8 x 1 = 8 If both number are 1, then the product is 1 1 x 1 = 1 https://www.tiwariacademy.com/ncert-solutions/class-6/maths/chapter-2/
If only one number be 1 then the product cannot be 1.
Examples: 5 x 1 = 5, 4 x 1 = 4, 8 x 1 = 8
If both number are 1, then the product is 1
1 x 1 = 1
Yes, if we multiply any number with zero the resultant product will be zero. Example: 2 x 0 = 0, 5 x 0 = 0, 9 x 0 = 0 If both numbers are zero, then the result also be zero. 0 x 0 = 0 https://www.tiwariacademy.com/ncert-solutions/class-6/maths/chapter-2/

Supply of milk in morning = 32 litres Supply of milk in evening = 68 litres Total supply = 32 + 68 = 100 litres Now Cost of 1 litre milk = ₹15 Cost of 100 litres milk = 15 x 100 = ₹1500 Therefore, ₹1500 is due to the vendor per day. https://www.tiwariacademy.com/ncert-solutions/class-6/maths/chapterRead more
Supply of milk in morning = 32 litres
Supply of milk in evening = 68 litres
Total supply = 32 + 68 = 100 litres
Now
Cost of 1 litre milk = ₹15
Cost of 100 litres milk = 15 x 100 = ₹1500
Therefore, ₹1500 is due to the vendor per day.
Study the pattern: 1 x 8 + 1 = 9; 12 x 8 + 2 = 98; 123 x 8 + 3 = 987, 1234 x 8 + 4 = 9876; 12345 x 8 + 5 = 98765 Write the next two steps. Can you say how the pattern works?
123456 x 8 + 6 = 987654 1234567 x 8 + 7 = 9876543 Pattern works like this: 1 x 8 + 1 = 9 12 x 8 + 2 = 98 123 x 8 + 3 = 987 1234 x 8 + 4 = 9876 12345 x 8 + 5 = 98765 123456 x 8 + 6 = 987654 1234567 x 8 + 7 = 9875643 https://www.tiwariacademy.com/ncert-solutions/class-6/maths/chapter-2/
123456 x 8 + 6 = 987654
1234567 x 8 + 7 = 9876543
Pattern works like this:
1 x 8 + 1 = 9
12 x 8 + 2 = 98
123 x 8 + 3 = 987
1234 x 8 + 4 = 9876
12345 x 8 + 5 = 98765
123456 x 8 + 6 = 987654
1234567 x 8 + 7 = 9875643
