Mathematics Operations and Symbols
+
plus sign /
addition sign
the notion of positive
Any number bigger than zero is a positive number and
can be written with or without a plus sign in front of it.
Thus, +5 (plus five) and 5 (five) are the same number
the operation of addition
3 + 5 = 8
three plus five equals eight
five added to three makes eight
three added to five makes eight
if you add five to three you get eight
Addition gives us a
sum
. In 3 + 5 = 8, the sum is eight.
-
minus sign /
subtraction
sign
the notion of negative
Any number smaller than zero is a negative number and
is written with a minus sign in front of it.
-3
minus three
the operation of subtraction
8 - 5 = 3
eight minus five equals three
five subtracted from eight equals three
if you subtract five from eight you get three
if you take five from eight you get three
Subtraction gives us a
difference
. In 8 - 5 = 3, the
difference is three
×
times sign /
multiplication
sign
multiplication
5 x 6 = 30
five times six equals thirty
five multiplied by six equals thirty
five sixes are thirty
if you multiply 5 by 6 you get thirty
Multiplication gives us a
product
. In 5 x 6 = 30, the
product is thirty
÷ OR /
division sign
division
15 ÷ 3 = 5
15 / 3 = 5
fifteen divided by three equals five
five goes into fifteen three times
if you divide fifteen by three you get five
if you divide three into fifteen you get five
Division gives us a
quotient
. In 15 ÷ 3 = 5, the quotient is
five
Pro Tip
=
equals sign
The
equals sign
represents
equality
:
3 + 4 = 7
three plus four equals seven
Note that we usually say
equals
NOT equal:
two plus two
equals
four
two plus two equal four
<
less than
3 < 4
three is less than four
>
greater than
4 > 3
four is greater than three
≠
NOT equal to
x ≠ z
x is not equal to z
≥
greater than
or equal to
x ≥ z
x is greater than or equal to z
≤
less than or
equal to
z ≤ x
z is less than or equal to x
