How can I perform maths in a silverstripe template?

I wish this helpful for you I come from a Rails background and am working on a Silverstripe 3.7 project on PHP 7.1 where I need to make a change to a template to fix a column alignment issue. , The code below should work.
Template:
code :
<div class="row">
    <% loop $ProductSectionBlocks %>
        <% if $Top.ProductSectionBlocksMod != 0 && $Top.ProductSectionBlocksMod == $FromEnd %>
            <%-- Bootstrap ^4 offset --%>
            <%--<div class="col-sm-4 offset-sm-{$Top.ProductSectionBlocksOffset}">--%>

            <%--Bootstrap 3 offset--%>
        <div class="col-sm-4 col-sm-offset-{$Top.ProductSectionBlocksOffset}">
            Column #{$Pos}
        <% else %>
        <div class="col-sm-4">
            Column #{$Pos}
        <% end_if %>
    </div>
    <% end_loop %>
</div>
public function getProductSectionBlocks()
{
    return Page::get()->limit(5); // Replace 'Page' with your real DataObject
}

public function ProductSectionBlocksMod()
{
    return ($this->getProductSectionBlocks()->count() % 3);
}


public function ProductSectionBlocksOffset()
{
    return 6 - ($this->ProductSectionBlocksMod() * 2);
}

MySQL optimization: Perform Maths operation inside or outside of a query?


By : Yuval Cohen

Does that help My feeling would be that doing the maths in the database would be slightly more efficient in the long run, given your query setup. With the select a,b,c version, PHP has to create 3 elements and populate them for each row fetched.
With the in-database version, only 2 elements are created, so you've cut creation time by 33%. Either way, the calculation has to be done, so there's not much in the way of savings there.

How can I randomly choose a maths operator and ask recurring maths questions with it?

hope this fix your issue There is a function in Python called eval() that evaluates strings which contain mathematical expressions.
code :
import random

ops = ['+', '-', '*', '/']
num1 = random.randint(0,12)
num2 = random.randint(0,10)
operation = random.choice(ops)

print(num1)
print(num2)
print(operation)

maths = eval(str(num1) + operation + str(num2))

print(maths)

Determine data type and perform maths on int and float columns

like below fixes the issue The reason it is only working for the first column is because of the way you iterate over the csv reader object:
you have a while loop that you intended to iterate over the columns, but inside that loop, just before the if-clause, you are also each time calling reader.next(), which will return the next line in the file. That means you would only be checking the elements on the diagonal of this csv file if it weren't for the actions that are happening in the if-clause. In the if-clause, you are then iterating over all the rows in the file, the reader object is an iterator which means that once you've obtained an element (e.g. a line), there's no way to get it again (you can't jump back to line 1 e.g. if you've already looked at line 2).
