$$99 \cdot 19 \sqrt{2} / 9 {(\frac{2}{100} 5 \sqrt{5})} 6 - 5 + 2 \cdot 99 \cdot 0.9961946980917455$$

Immultiplika 19 u 99 biex tikseb 1881.

$$6\times \frac{1881\sqrt{2}}{9}\times 5\times \frac{2}{100}\sqrt{5}-5+2\times 99\times 0.9961946980917455$$

Iddividi 1881\sqrt{2} b'9 biex tikseb209\sqrt{2}.

$$6\times 209\sqrt{2}\times 5\times \frac{2}{100}\sqrt{5}-5+2\times 99\times 0.9961946980917455$$

Immultiplika 6 u 209 biex tikseb 1254.

$$1254\sqrt{2}\times 5\times \frac{2}{100}\sqrt{5}-5+2\times 99\times 0.9961946980917455$$

Immultiplika 1254 u 5 biex tikseb 6270.

$$6270\sqrt{2}\times \frac{2}{100}\sqrt{5}-5+2\times 99\times 0.9961946980917455$$

Naqqas il-frazzjoni \frac{2}{100} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 2.

$$6270\sqrt{2}\times \frac{1}{50}\sqrt{5}-5+2\times 99\times 0.9961946980917455$$

Immultiplika 6270 u \frac{1}{50} biex tikseb \frac{6270}{50}.

$$\frac{6270}{50}\sqrt{2}\sqrt{5}-5+2\times 99\times 0.9961946980917455$$

Naqqas il-frazzjoni \frac{6270}{50} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 10.

$$\frac{627}{5}\sqrt{2}\sqrt{5}-5+2\times 99\times 0.9961946980917455$$

Biex timmultiplika \sqrt{2} u \sqrt{5}, immultiplika n-numri taħt l-għerq kwadrat.

$$\frac{627}{5}\sqrt{10}-5+2\times 99\times 0.9961946980917455$$

Immultiplika 2 u 99 biex tikseb 198.

$$\frac{627}{5}\sqrt{10}-5+198\times 0.9961946980917455$$

Immultiplika 198 u 0.9961946980917455 biex tikseb 197.246550222165609.

$$\frac{627}{5}\sqrt{10}-5+197.246550222165609$$

Żid -5 u 197.246550222165609 biex tikseb 192.246550222165609.

$$\frac{627}{5}\sqrt{10}+192.246550222165609$$

Fattur

$$\frac{125400000000000000 \sqrt{10} + 192246550222165609}{1000000000000000} = 588\frac{796168807280384}{1000000000000000} = 588.7961688072804$$
