2-1+629•478

To solve the expression \(2 - 1 + 629 \times 478\): 1. First, calculate \(629 \times 478\): \[ 629 \times 478 = 300,862 \] 2. Now substitute back into the expression: \[ 2 - 1 + 300,862 \] 3. Next, simplify \(2 - 1\): \[ 2 - 1 = 1 \] 4. Finally, add \(1 + 300,862\): \[ 1 + 300,862 = 300,863 \] So, the final result is: \[ \boxed{300863} \]
