Addition, Same Power of 10

Add each pair (both already share the same power of 10). Enter the resulting coefficient as a decimal.

$(4.5 \times 10^{2}) + (2.7 \times 10^{2})$

$(4.4 \times 10^{6}) + (4.1 \times 10^{6})$

$(3.2 \times 10^{2}) + (1.7 \times 10^{2})$

$(4.7 \times 10^{8}) + (3.8 \times 10^{8})$

$(2.4 \times 10^{5}) + (1.3 \times 10^{5})$

$(4.8 \times 10^{8}) + (1.4 \times 10^{8})$

Subtract each pair (both already share the same power of 10; the first is always larger). Enter the resulting coefficient as a decimal.

$(6.1 \times 10^{5}) - (2.2 \times 10^{5})$

$(9 \times 10^{4}) - (7 \times 10^{4})$

$(9 \times 10^{4}) - (5.6 \times 10^{4})$

$(5.5 \times 10^{7}) - (2.8 \times 10^{7})$

$(9.1 \times 10^{8}) - (5.8 \times 10^{8})$

$(7.2 \times 10^{6}) - (3.5 \times 10^{6})$
