Solve [(40*30)+40+23:10]+42=

$$[ ( 40 \times 30 ) + 40 + 23 : 10 ] + 42 =$$

Evaluate

$$\frac{12843}{10}=1284.3$$

Solution Steps

Multiply 40 and 30 to get 1200.

$$1200+40+\frac{23}{10}+42$$

Add 1200 and 40 to get 1240.

$$1240+\frac{23}{10}+42$$

$$\frac{12423}{10}+42$$

Convert 42 to fraction \frac{420}{10}.

$$\frac{12423}{10}+\frac{420}{10}$$

Since \frac{12423}{10} and \frac{420}{10} have the same denominator, add them by adding their numerators.

$$\frac{12423+420}{10}$$

Add 12423 and 420 to get 12843.

$$\frac{12843}{10}$$

Factor

$$\frac{3 ^ {2} \cdot 1427}{2 \cdot 5} = 1284\frac{3}{10} = 1284.3$$
