How do I push to the calculator page and active in tabs page

Hi there!

I’m facing some problem in my project.

Picture above was my tabs.html

Picture above was my tabs.ts

Then this is my home page

The thing I want was when I click the loan calculator button at my home page, it will jump to the loan calculator page at the tabs there.
Like below

It shows that I’m now locate at the home page not the calculator page.

Please help me!!
