what is 7x8
everyone knows that 8*8 = 64
so take off an eight
64 - 8 = 56
everyone knows that 7*7 = 49
so add on a seven
49 + 7 = 56
actually, "everyone knows" that 7x8 = 56
How about 42 + 14 ?
To find the product of 7 and 8, you need to multiply them together.
To calculate this manually, you can use the standard multiplication method:
- Start by multiplying the units place of the second number (8) with the first number (7). In this case, 8 multiplied by 7 equals 56.
- Then, move to the tens place of the second number and multiply it by the first number. In this case, 8 multiplied by 7 equals 56 again.
- Finally, add the two results together. 56 + 56 equals 112.
Therefore, 7 multiplied by 8 equals 112.
