Question

Answer 1

a) \(208-108.\left(-3\right)^2-299\)

\(=208-108.\left(-9\right)-299\)

\(=208-\left(-972\right)-299\)

\(=208+1271\)

\(=1479\)

b) 

Answer 2

\(b,=\left(-121\right).65+65.\left(-53\right)-65.26\\ =65.\left[\left(-121\right)+\left(-53\right)-26\right]\\ =65.\left(-200\right)=-13000\)

Answer 3

a) 

b) (−121).65+65.(−53)−65.26

=−13000

c) (-427-175)-(-327+25-48)

 =-252
