= 10^7+10^11
= 10×10×10×10×10×10×10 + 10×10×10×10×10×10×10×10×10×10×10
= 10,000,000 + 100,000,000,000
= 100,010,000,000
= 10×10×10×10×10×10×10 + 10×10×10×10×10×10×10×10×10×10×10
= 10,000,000 + 100,000,000,000
= 100,010,000,000

10^(-7) = 1 / 10000000 or 0.0000001
10^(-11) = 1 / 100000000000 or 0.00000000001
Add 0.0000001 and 0.00000000001 to get
0.00000010001 or 1.001e-7 in scientific notation
