Solve 1*3+3*5+5*7++35*37+37*39div39*41

$$1 \times 3 + 3 \times 5 + 5 \times 7 + + 35 \times 37 + 37 \times 39 \div 39 \times 41$$

Evaluate

$$2865$$

Solution Steps

Multiply 1 and 3 to get 3. Multiply 3 and 5 to get 15. Multiply 5 and 7 to get 35. Multiply 35 and 37 to get 1295.

$$3+15+35+1295+\frac{37\times 39}{39}\times 41$$

Add 3 and 15 to get 18.

$$18+35+1295+\frac{37\times 39}{39}\times 41$$

Add 18 and 35 to get 53.

$$53+1295+\frac{37\times 39}{39}\times 41$$

Add 53 and 1295 to get 1348.

$$1348+\frac{37\times 39}{39}\times 41$$

Cancel out 39 and 39.

$$1348+37\times 41$$

Multiply 37 and 41 to get 1517.

$$1348+1517$$

Add 1348 and 1517 to get 2865.

$$2865$$

Factor
