The answer is 112. Simply add the numbers together arithmetically as you would for the problem two plus two. To check your work, a calculator is the best option.
67 plus 3 equals 70.
12 + 23 + 45 + 67 + 16 + 18 + 45 = 226
45 - 78 + 67 + 1904 + 6879 = -8,883
To find the product of 45 multiplied by 67, you would multiply the two numbers together. 45 multiplied by 67 equals 3015. This can be calculated by multiplying 45 by 60 (which equals 2700) and then multiplying 45 by 7 (which equals 315) and adding the two results together.
