Simplify: $1-(1*2)+-1$?

2. anonymous

no its one half times 1 times two plus negative 1

All right: $\frac{1}{2}(1\cdot 2)+-1$ Multiplicative identity: $\frac{1}{2}(1\cdot 2)+-1=\frac{1}{2}(2)+-1$Definition of Multiplicative Inverse: $\frac{1}{2}(2)+-1=1+-1$Definition of Additive inverse: $1+-1=0$
