a. \(125.\left(-24\right)+24.225\)

\(=24.\left(-125+225\right)\)

\(=24.100\)

\(=2400\)

b. \(26.\left(-125\right)-125.\left(-36\right)+125.\left(-7\right)\)

\(=\left(-26\right).125-125.\left(-36\right)+125.\left(-7\right)\)

\(=125.\left[\left(-26\right)-\left(-36\right)+\left(-7\right)\right]\)
