Answer 2

1. The expression "ab + c" is a simple algebraic expression. It consists of two variables, "a" and "b," and a constant term "c." The expression indicates that the variables "a" and "b" are being multiplied together and then added to the constant term "c." For example, if we have "a = 2," "b = 3," and "c = 4," we can substitute these values into the expression and evaluate it as follows:

"ab + c"

"2 * 3 + 4"

"6 + 4"

"10"

2. The expression "da" is another algebraic expression, where "d" and "a" are variables. This expression indicates that the variable "d" is being multiplied by the variable "a." For example, if we have "d = 5" and "a = 2," we can substitute these values into the expression and evaluate it as follows:

"da"

"5 * 2"

"10"

3. The expression "Sa + 6²" is a combination of algebraic terms and arithmetic operations. Here, "S" and "a" are variables, and "6²" represents the square of 6. The expression indicates that the variable "S" is being multiplied by the variable "a" and then added to the square of 6. For example, if we have "S = 3" and "a = 4," we can substitute these values into the expression and evaluate it as follows:

"Sa + 6²"

"3 * 4 + 6²"

"12 + 36"

"48"

4. The expression "g(b+c)" involves variables and parentheses. Here, "g" represents a variable, and "b" and "c" are also variables. The expression indicates that the variables "b" and "c" are being added together, and the result is then multiplied by the variable "g." For example, if we have "g = 2," "b = 3," and "c = 4," we can substitute these values into the expression and evaluate it as follows:

"g(b+c)"

"2(3+4)"

"2(7)"

"14"

5. The expression "74-28" is a simple subtraction problem. Here, we have the numbers 74 and 28, and we need to subtract 28 from 74.

"74-28"

"46"

6. The expression "be - e" involves variables and subtraction. Here, "b" and "e" are variables. The expression indicates that the variable "e" is being subtracted from the variable "b." For example, if we have "b = 5" and "e = 2," we can substitute these values into the expression and evaluate it as follows:

"be - e"

"5 * 2 - 2"

"10 - 2"

"8"

7. The expression "-12" is a simple numerical expression. It represents the number negative 12.
