Question

3. Simplify:
(1-2)(¹-3) (1-4)-(1-99) (1-700)

Answer 1

We can simplify this expression by using the order of operations (PEMDAS) and distributing the negative sign:

(1-2)(¹-3) (1-4)-(1-99) (1-700) = (-1)(-2) (-2)-(1-99) (-699)

Simplifying further, we have:

(-1)(-2) = 2
(-2)-(1-99) = -2 - (-98) = 96
(-699) = -699

Putting it all together, we get:

2*96 - (-699) = 192 + 699 = 891

Therefore, the simplified expression is 891.
