$4.1 \cdot 10^{- 2} - 2.6 \cdot 10^{- 3}$

Step 1

Move the decimal point in $- 2.6$ to the left by $1$ place and increase the power of $10^{- 3}$ by $1$ .

$4.1 \cdot 10^{- 2} - 0.26 \cdot 10^{- 2}$

Step 2

Factor $10^{- 2}$ out of $4.1 \cdot 10^{- 2} - 0.26 \cdot 10^{- 2}$ .

$(4.1 - 0.26) \cdot 10^{- 2}$

Step 3

Subtract $0.26$ from $4.1$ .

$3.84 \cdot 10^{- 2}$
