Basic Math Examples

$4.2 i - 2.3 i + (7.2 - 7.7 i) - (6.67 i)$

Step 1

Remove parentheses.

$4.2 i - 2.3 i + 7.2 - 7.7 i - (6.67 i)$

Step 2

Multiply $6.67$ by $- 1$ .

$4.2 i - 2.3 i + 7.2 - 7.7 i - 6.67 i$

Step 3

Subtract $2.3 i$ from $4.2 i$ .

$1.9 i + 7.2 - 7.7 i - 6.67 i$

Step 4

Subtract $7.7 i$ from $1.9 i$ .

$7.2 - 5.8 i - 6.67 i$

Step 5

Subtract $6.67 i$ from $- 5.8 i$ .

$7.2 - 12.47 i$
