From the Table of 10, we know that:
10 times 4 is equal to 10 multiplied by 4, which equals 40.
10 times 10 is equal to 10 multiplied by 10, which equals 100.
Therefore, the sum of 10 times 4 and 7 times 10 is equal to 10 multiplied by 4 plus 10 multiplied by 10, which simplifies to 40 plus 100, resulting in a final answer of 140.
