Solve 18div6+4div2-15div3+4-2div-1

$$18 \div 6+4 \div 2-15 \div 3+4-2 \div -1$$

Evaluate

$$6$$

Solution Steps

Divide 18 by 6 to get 3.

$$3+\frac{4}{2}-\frac{15}{3}+4-\frac{2}{-1}$$

Divide 4 by 2 to get 2.

$$3+2-\frac{15}{3}+4-\frac{2}{-1}$$

Add 3 and 2 to get 5.

$$5-\frac{15}{3}+4-\frac{2}{-1}$$

Divide 15 by 3 to get 5.

$$5-5+4-\frac{2}{-1}$$

Subtract 5 from 5 to get 0.

$$4-\frac{2}{-1}$$

Fraction \frac{2}{-1} can be rewritten as -2 by extracting the negative sign.

$$4-\left(-2\right)$$

The opposite of -2 is 2.

$$4+2$$

Add 4 and 2 to get 6.
