subgroup
sous groupe m

A subgroup. The group H whose elements form a subset of the group G and share the same operation with G is called a subgroup of G.

For example:

The set (0.1,2,3) in the sum of size 4 is a group.

The subset (0.2) in the same operation forms a subgroup.

subset
sous-ensemble m

A subset. If the set B contains elements that are members of another set A, B is called a subset of A (written BCA or ADB). All sets are subsets of the universal set 8 and the empty set is a subset of each set.

If A contains elements that are not found in B, then B is a proper subset of A.

substitution
substitution f

Substitution. Substitution in mathematics is the substitution of one expression for another in order to simplify. Substituting a number for a variable - for example - substituting 3=x in the equation 1+2x = y which gives =2 3+1 x2 gives Substitution is used especially to facilitate certain integrals, for example.

subtend
sous - tendre

subtend. An angle is subtended by an arc or line when it
stands on the arc or line.

In the figure below, the arc AB subtends the angle. at the circumference of the circle and the angle 0 at the center.

subtraction
soustraction f

Subtraction. One of the four basic operations of arithmetic. It is concerned with cases in which one quantity is removed from another quantity or when calculating the difference between two quantities. Subtraction is the inverse operation of addition.

sufficient
suffisant

كّّ. If we consider the statement "If x equals 3 and y equals 4, then x+y equals 7", we find ourselves facing two conditions:

(1) and ( x equals 3 and y equals 4 )
(2) and ( x+y equals 7 )

The first condition (1) is sufficient to satisfy the second condition (2), but the second condition (2) is not sufficient to satisfy the first.

sum
somme f

Sum. The result of adding two or more quantities.
