Answer 2

It looks like you've provided a series of mathematical equations and expressions. Let's break down each step:

1. (435 - 418) = 70 This equation is not correct. The result of 435 - 418 is 17, not 70.

2. 435 - 418 = 7 This is correct. 435 minus 418 does equal 7.

3. 446 - 418 = 80 This is also correct. 446 minus 418 does equal 80.

4. (435 - 418) × ÷ (435 - 418) = 70 This equation is not mathematically valid. You can't divide by zero, and in this case, both the numerator and denominator are 17 (since 435 - 418 equals 17). So, the correct expression would be 17 ÷ 17, which equals 1, not 70.

5. 70 = 70 This is a true statement. 70 is indeed equal to 70.

In summary:

• The first equation (435 - 418) = 70 is incorrect.
• The second equation 435 - 418 = 7 is correct.
• The third equation 446 - 418 = 80 is correct.
• The fourth equation (435 - 418) × ÷ (435 - 418) = 70 is not mathematically valid and should be 17 ÷ 17 = 1.
• The last equation 70 = 70 is true.
