Question

Simplify: (−415)* (−41) + (−415)* 31 + (−415)*20

Answer 1

Answer:

If you add 1 to a natural number, we get its successor. If you subtract 1 from a natural number, you get its predecessor. 

Every natural number has a successor.

Every natural number except 1 has a predecessor.

Every whole number has a successor.

Every whole number except zero has a predecessor.

All natural numbers are whole numbers, but all whole numbers are not natural numbers.

Step-by-step explanation:

The chapter starts with the introduction on predecessor and successor followed by concept of whole numbers.

Answer 2

Answer:

-4150

Step-by-step explanation:

This is simplification so first we will use BODMAS(Bracket,Of, Divide, Multiply, Addition, Substraction) rule so first we will multiply because here is nothing to divide

so,(-415)*(-41) = 17015 and (-415)*31 = -12865 and (-415)*20 = -8300

Now we will add all

so, 17015+(-12865)+(-8300) = -4150

l hope you understand it clearly.
