Solve the following expression.
$$ 5.6 - \left\{2 + 0.6 of (2.1 - 2.6 \times 1.12)\right\}$$
Solution
$$ 5.6 - \left\{2 + 0.6 of (2.1 - 2.6 \times 1.12)\right\}$$
= $$ 5.6 - \left\{2 + 0.6 of (2.1 - 2.912)\right\}$$
= $$ 5.6 - \left\{2 + 0.6 \times (-0.812)\right\}$$
= $$ 5.6 - \left\{2 - 0.4872\right\}$$
= 5.6 - 1.5128 = 4.0872
