Explanation Given information: The expression is 10.2 − 6.7 . Explanation: Use the below steps to subtract: 1) Write the second number below the first number as the decimal places are lined up. 2) Now, place the subtraction sign on the left of the second number. 3) Now, subtract as whole numbers. Now, solving 10.2 − 6.7 , Line up the decimal points. 1 0 . 2 − 6 . 7 _ Then, subtract the digits from right to left as whole numbers. Subtract the first-place digits right to the decimal. Since 7 is larger than 2 , so borrow 1 ones from ones place. But at ones place there is 0 , so borrow 1 ten from tens place. Thus, at tens place 1 becomes 1 − 1 = 0 , one’s place digit 0 becomes 0 + 10 − 1 = 9 , and at tenth place 2 becomes 2 + 10 = 12 . 9 0 10 12 _ 1 0 . 2 − 6 . 7 _ Subtract 7 from 12 , that is, 12 − 7 = 5 . 9 0 10 12 _ 1 0 . 2 − 6 . 7 _ 5 Now, place the decimal as the other numbers have. 9 0 10 12 _ 1 0

Family of Curves

A family of curves is a group of curves that are each described by a parametrization in which one or more variables are parameters. In general, the parameters have more complexity on the assembly of the curve than an ordinary linear transformation. These…

XZ Plane

In order to understand XZ plane, it's helpful to understand two-dimensional and three-dimensional spaces. To plot a point on a plane, two numbers are needed, and these two numbers in the plane can be represented as an ordered pair (a,b) where a and b are…

Euclidean Geometry

Geometry is the branch of mathematics that deals with flat surfaces like lines, angles, points, two-dimensional figures, etc. In Euclidean geometry, one studies the geometrical shapes that rely on different theorems and axioms. This (pure mathematics) ge…
