these are small question..i need proceduee for all plz

Rules: 1) When the decimal is present, start counting from the left. 2) When the decimal is absent, start counting from the right. 3) Zeroes encountered before a non zero digit do not count. Q1) Addition and subtraction: Answer e.g. 1,0+1.00-1.0 (2)x: 2 is a number of significant fig (SF) *0.1 point/each (a) 141.1+0.32 (b) 108.030+3.2 (c) 1.01-0.6 (d) 45.392-1 02) Multiplication and division: Answer e g. 1.01 x 1.0-1.0 (2): 2 is a number of SF: 0.1 point/leach (a) 141.1+0.32 (b) 108.030x3.2 (c) 1.01+0.6 (d) 45.392x1 Q3) Addition, subtraction, multiplication, and division: the same above: \"0.1 point/each (a) 141.1+0.32-1.00 (b) 108.030x3.2-0.0 (c) 1.01+0.6+3.1 (d) 45.392×1+1 Q4) Express 5,510,000 in scientific notation (e.g. 1.0x10): use round-up. *0.1 point/each a. with I significant figure b. with 2 significant figures c. with 3 significant figures d. with 4 significant figures Q5) Express 0.0003711 in scientific notation (e.g., 1.0x10). *0.1 point/each a. with I significant figure b. with 2 significant figures c. with 3 significant figures d. with 4 significant figures

Solution

1 a) 141.1 + .32 = 141.42   ( 5 significan digits )

b) 108.030 + 3.2 = 111.23 ( 5 significan digits )

c) 1.01 - .6 = .41 ( 2 significan digits )

d) 45.392 - 1 = 44.392 ( 5 significan digits )

2. a) 141.1 / .32 = 440.9375 ( 7 significan digits )

b) 108.030 * 3.2 = 345.696   ( 6 significan digits )

c) 1.01 / .6 = 1.6833 ( 5 significan digits )

d) 45.392 * 1 = 45.392 ( 5 significan digits )

3 a) 141.1 / .32 - 1 = 439.9375 ( 7 significan digits )

b) 108.030 * 3.2 - 0.0 = 345.696 ( 6 significan digits )

c) 1.01 / .6 + 3.1= 1.6833 + 3.1 =4.7833 ( 5 significan digits )

d) 45.392 * 1 + 1 = 46.392 ( 5 significan digits )
