Hello friends on this wonderful platform.
Good morning to all members of this great platform, hope you all doing well over there,
It's another beautiful day, for us to know this moment is a great opportunity that we have received our God.
Many people wish to know this moment of life but the opportunity was not given, I thank God Almighty that giving us this enormous opportunity I love my God very much he loves me very broadly.
Back to today routine
Mathematics is very essential in daily activities, most it's very significant for all students to know the basic knowledge of mathematics.
Let discuss the nature of mathematics. mathematics was derived from the Greek word ‘mathenein’ meaning learning, and ‘techne’ means an art of technique. mathematics is a science of discovery, an intellectual game, a tool subject, involves a spontaneous method, many things define mathematics. But most importantly is that mathematics isn't all about solving, we can also apply mathematics in our everyday life.
There are many students in the schools and colleges of our country nowadays, whose status worsens when they hear the name called mathematics. Not only in school-college, but also in University.
Many people are scared of mathematics but it's not the same. Some may be afraid to solve mathematical problems, some may be afraid to just do math tests. But whatever the reason for the fear, you can overcome your fear of mathematics if you want. Am ready to share with you all the steps need to solve any mathematics problems. I will post any topic of mathematics on this platform every day with a good explanation...
No time to wait
Let something good
Class: preferable for jss2
Topic: word problem
Reference book: essential mathematics for jss3 by A.J.S. Oluwasanmi.
Objective: By the end of the students should be able to understand the topic.
Presentation: The teacher presents the lesson on the following contents
Word problem
Word problem process in which words are translated in numerical expression.
A term used in a word problem
- sum means plus(+)
2)difference means minus(-) - product or of means multiplication(×)
4)divide means division(÷)
5)quarter means 4
EXAMPLE
example1: when 30 is added to a number the result is -18. Find the number
Solution
The first thing to do or come to your mind is this.
It was stated that when 30 is added to a number,
You know that the number was not given, okay, represent them by any letter you like.
For me, I prefer using y.
Now
Let the number be y
So, read the question again till you understand it.
Look, this or slit it like this.
when 30 is added to a number, it means
30 added to the number
From above I said let the number be y
So, it can interpret as below
Y + 30
And then continue reading the next words,
(the result is -18)
Which says that the result of Y + 30 is -18.
Therefore;
Y+30=-18 •••••••••••••••••(1)
Now, from equation (1)
Make Y the subject of the formula
The +30 will cross to another side while crossing +30 changes to -30, then it becomes below
Y=-18-30•••••••••••••••••••(2)
From equation 2, you will note that minus(-) is common to -18 and -30, so, pick one (-) out, it becomes below.
Y=-(18+30)•••••••••••••••(3)
From equation 3 if you open the bracket with - you will get equation 2 back. Because if you use the rules in mathematics below,
- -×- =+
- -×+ or +×- = -
.
Form equation 3
Add 18+ 30 =48
Therefore, it becomes
Y=-48.
So now the answer is -48.
Which shows that the number is -48.
