Answer 2

Let's solve each of these expressions one by one:

(1) 0:2412+456*1-78:1+354x0

We first need to evaluate the division and multiplication operations.

0:2412 = 0, since 0 divided by any non-zero number is 0.

78:1 = 78, since dividing by 1 doesn't change the value.

354x0 = 0, since anything multiplied by 0 is 0.

So now we can substitute these values back into the original expression:

0 + 456*1 - 78 + 0 = 378

Therefore, the value of the expression is 378.

(2) 678-125x5+781x0x1

Multiplication has higher precedence than addition or subtraction, so we need to evaluate the multiplication first.

781x0x1 = 0, since anything multiplied by 0 is 0.

125x5 = 625, since 125 multiplied by 5 is 625.

Now we can substitute these values back into the original expression:

678 - 625 + 0 = 53

Therefore, the value of the expression is 53.

(3) 1000-456x104+8907x0

Again, multiplication has higher precedence than addition or subtraction.

456x104 = 47344, since 456 multiplied by 104 is 47344.

8907x0 = 0, since anything multiplied by 0 is 0.

Now we can substitute these values back into the original expression:

1000 - 47344 + 0 = -46344

Therefore, the value of the expression is -46344.

(4) 0;4567-4399+56x42

I'm not entirely sure what the ";" operator is supposed to do here, so I will assume it is a typo and ignore it.

Multiplication has higher precedence than addition or subtraction, so we need to evaluate the multiplication first.

56x42 = 2352, since 56 multiplied by 42 is 2352.

Now we can substitute this value back into the original expression:

4567 - 4399 + 2352 = 2520

Therefore, the value of the expression is 2520.
